every tuner has their share of groupies and fan boys so of course everyone is gonna recommend different tuners and say something bad about another.

go with whoever you feel comfortable with, suits your budget and is near you (unless you don't mind travelling further for them)

generally if the tuner is down to earth and friendly, it means good service. if they're pricks and think they're better than you just because they're a tuner, i'd walk away. (alot of big time workshops have this attitude cause you are just small fish and only need a tune).

i've used powertune before, wasn't the best experience/service, however Jez - wonderful service and a friendly fella, you will not be disappointed.

would've went to JEM before powertune but they couldn't fit me into their schedule,

Don't get too caught up with dyno figures though. I think JEMs dyno reads pretty low compared to others and also Adam will tune for excellent driveabilty for the street.

When I had mine retuned by JEM after adding a bigger exhaust and intercooler I was disappointed to see that the killer wasps had actually decreased compared to the number I got from a previous dyno (albeit a hub dyno).

Once I drove the car though, there was no doubt that the power had increased enormously all through the rev range.

Some places tune for Dyno numbers, Adam at JEM will tune for exceptional driveability and real world results.

Just my 2 cents :)

My post numbers are pretty low and I haven't quite figured out how to access this info. Are you able to help me out with where to find it?

I recommended JEM, perhaps, in retrospect, I should have just put: JEM +1 without any reasons or ellaboration as to why I would recommend them to help you out. If you look back over other comments none have provided reasons, I did. I also did not say they were better, as I have no experience with DVS.

The dyno figure seems high that "Envy" provided for -5s, coming from a qualified mechanic that has built a few. In fact, one of my builds is going to JEM next week that is extremely similar to what you have, hence the interest. Also, from past experience there is a lot more to a good tune than just an outright Kw figure. My intention was to draw the focus away from the outright figure, as this often leads to disappointment when there is no longevity factored into the tune for a street car where your expected outcome "is not 460kw but higher" on that set up.

The intention was to assist - the responses make me wonder why I bothered in the first place. Welcome to SA for the new guy! :/

wow 6 months thats not long at all :P decide to take my car to jem because of ur build with them

Haha nice! That is always a good thing :) I talk pretty highly of them, there is a lot of behind the scenes stuff they have done to get my car to where it is that is not shown on the forum etc...

In saying that, i also support the suggestions for DVS JEZ in here and always will as he has been nothing but willing to help for me and many other SAUers on here :D

Thanks for posting this. Could I impose for more detail about the set up that was tuned at Envy and whether it's exactly the same that is going to be tuned by JEM and some detail about motor?

Valves - [oversize or standard size]

Intake manifold and throttle/s [standard or oversize aftermarket]

Intercooler [what size brand]

Head - Ported and polished

Block - [standard or grout fill]

Oil pump - [brand]

water pump - [brand]

Turbos - -5s [what A/Rs and are they antisurge impeller housings]

Compression ratio

Exhaust system incl manifold

Crank - [standard, work done or aftermarket]

Pistons - [forged but are they teflon and/or ceramic treated]

Rods - [brand]

Wastegates - [standard or modified]

Fuel [E85, but what set up]

balancer - [standard or a/m]

A/C still on?

Computer [Haltech ?]

Any lightening of driveline components?

Was the car tuned in awd?

Sorry for the million and one questions, but this will make an awesome thread for others to get reliable data from once the new dyno sheet goes up. Thanks again.

      I'll probably be putting the shit box back on the dyno again soon, I want to dial in the closed loop boost control properly. I'll have a camera facing the car/motor for fun too. Just note, there are essentially 3x 10AN inlets going into the catch can and 1x going back to the intake pipe. Most of the time the catch can "return" to the sump actually is the crank case breather, pushing air out.

      I have the R3C with a Nismo slave and by no means does it behave like a stocker, it ain’t THAT bad. On take off just give a bit more throttle than you would say a coppermix and it’s fine. It will not slip though.

      Yet another RB Neo misfiring thread after reading all the others.

      Okay. Final round of testing done. Got a friend to hook up a fancy scanner to the car and we also ran some compression and leakdown tests, she is healthy.  The MAF was definitely the culprit. So for future reference anyone with similar issues that find this thread. I suggest the following steps, in order of affordability:   Check your spark plugs for any fouling, replace plugs if they are bad or re adjust the gaps making it narrower (0.8mm would be good). Check every coil's resistance with a multimeter. It can be done by probing the IB and G pins on the coil pack. Resistance should be around 1.4 (+/- 0.1) Ohms Check the MAF. If you have Nissan connect or a good scanner with the 14 adapter it should allow you to see the voltage on the MAF reading should be around 1.1 - 1.2V when car is idling. But if you don't, buy a new MAF from Amazon and test, then return it. (For instance, I got a Chinese one for $40 that was reporting 1.3v on idle). If you still have scanner, you can run tests on the injectors to see if they are working, just remember to unplug the fuel pump fuse/relay and have no pressure on the line. Then listen for the noises that the injectors make. Clean/replace injectors as needed. Once you find the issue and fix, order thousands of dollars worth of OEM parts to refresh unrelated things (Optional)   PS: Thanks to the absolute legends of this forum for the responses and help to someone that went a bit over their head.
