Hey Peeps,

Just thought Id post up my experience with DVS JEZ last night.

I have had my car off the road for a year after deciding to do an overhaul and cleanup, but as things always go I have had to get the car going as it is needed for daily duties for a while.

Last week I got in contact with DVS JEZ and explained to him my situation and that I needed a tune done on my new mods fairly quickly as I am a little pressed for time. He was able to book out a dyno and fit me in last night so off I drove up to the central coast for what we thought would be a quick 2 hour tune.

For the first couple of runs all was good and and it seemed that we were going to have an easy night, then the trouble started >_<

Every time we ramped up the car it wasnt getting full boost till around 4300+ rpm and was making a massive 140odd rwkw......"WOW, the thousands of dollars spent really have paid off" we joked and started the process of tracking down what was causing the power loss and massive lag.

So we at first thought the wastgate wasnt holding closed so we took the dump of to have a look, if any of you have seen how the Pro S kit is put together you would realise this is NOT an easy task. We found what we though was a little bit of a dodgy seal on the Wastgate flap but JEZ was concinced that this wasnt the cause of our problem.

Off went the cat, and even though it lookied ok we straight away gained heaps of power every where so that was the culprit. After it was fixed we spent the next couple of hours fine tuning and I couldnt be happier with the results

277kw @18 psi with plenty more in but we thought being a daily for now and as the weather is getting hotter it was really nice and safe at this level.

I cannot thank JEZ (and Boydy) :worship: enough for the time and effort they put in last night, we were up there tuning till 1am and the guys were more than happy to finish the job, even when I offered to let them just rough it up for now and then we can finish it off later.

I am so impressed with his workmanship and the way he explained everything to me as he went along, made me feel very comfortable leaving my pride and joy in his hands.

And as for the HKS Huffer, all I can say is......WOW What a turbo, this thing just is so dam responsive and has power everywhere, Im glad i searched for so long to get iit and didnt settle for anythging else, IMO HKS can really justify the heavy price tag.

Anyway enough babbling and time for the list of mods and the dyno sheet.

Thanks guys, I just cant get over how smooth and responsive this turbo feels.

It actually gets onto boost better than my HG highflow, btw Hamish we were referencing your graph last night when we first had dramas so thanks man haha

WOW what a night, glad we worked through the little issue's, cause once they were sorted the power was appearing more and more,

277kw without reaching the knock limit of the motor on only 18psi, i am very impressed with the setup u have built dave, all the hard work u have put into it really shows.

One of the nicest engine bays i have seen, I can't believe how cool the plenum was after continous runs, The Craved coatings work a treat.

Then the road test. Dave was nice enough to let me take his car for a squirt up the road, makes mince meat of his semi slicks with near stock response. 16psi at 3100 was very impressive.

E85 would be good to see next, well once its more readily available and ur little 555cc injectors have been upgraded

Made mince meat of the slicks a few times on the way home too Jez ;)

Hope your boss was ok with you having such a late night.

I was having a chuckle to my mate this morning on how careful you were being around the bay so as to not scratch the coatings.

You were right about the cai too man, gave it a bootfull on mooney mooney bridge from a slow start at the bottom in forth and it kind of choked up at around 5k for a second, you could definately tell it wasn't getting enough air.

I'll make the hole 3 or 3.5 inch

Sounds about right. I can hold 0.8bar to redline on low boost. It's good if the gf drives it :P but then even on that boost it's quick LOL.

Im thinking a little more preload on the actuator might stop these turbos falling off boost high in the revs. Every dyno sheet over 18psi does it :(

Was plenty of preload, around 8mm atleast. Had a prick of a time getting it back on.

How was the hks heatshield aye. The bracket bolts to the the top dump pipe flange and looks like it stops the wastegate flapper arm from opening completely

    • Please use a modern ECU. PowerFC with the Nintendo Gameboy controller is horrible. It's not 2005 anymore.
    • The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.
    • Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

    • The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week
