Well I finally went and got a tune on my S2 33 gtst which had some decent stage 1 mods done to it. I ended up choosing a Wolf v500. Car has...

HKSGT2530

HKS FMIC

3" Turbo back exhaust

Hi flo cat

Fuel pump

Pod filter

Custom air intake

Car made 307rwhp before tune. Was boosting to 0.8 bar and running rich.

After the Wolf V500 was added to the car and dyno tuned (on same dyno, same tuner) it made the same 307rwhp boosting to 1 bar. The car also uses more fuel, has bad cold starts and has a dirty black carbon mark around the exhaust (after the tune) which i have had trouble removing.

In summary I have spent $3k on new ECU and tune for no gain in hp, worse starting, worse fuel economy, weakened engine and turbo (boosting higher) and not to mention the carbon stain on the rear bumber.

Should i be p*ssed considering there was no change? Or just realise that's the life of tuning cars?

Cheers.

DOH! its sounds like a bad tuner situation. take it back and get it sorted. to be honest though cold start can sometimes be a bitch if your stuck for time... ie not able to have car for a dead cold start.

Yes tuner has been paid.

The car had some custom jap piggyback unit in it before the tune. I think this was doing as good job as the wolf. Well now i know - $3k later!

The hp I have is the most a 2530 can handle anyway. I would need another exhaust manifold and larger turbo to go further. As stated by the tuner. I think he mis interpreted what turbo I had (he thought it was a 2540), thinking i would have 350rwhp.

Anyway I will continue to monitor the fuel. Any chance of how to remove the black mark from my bumper? Should I ask them to do it?

What you will find with the 2530 is that it will not make any more peak power but your torque and midrange will be huge the more boost you put into it.

I had the same experience with the 2535, it made no more peak power but on 18 - 19psi it was twice as quick as at 14psi

Silva33, Yes thats what the tuner said, and i think you are correct - I have gained torque and midrange. Will post before and after to verify. For those who have jumped to conclusions saying i have been "ripped" a 2530 will not make any more power than 300~hp.

Guilt-Toy, the car was broke it was running far too rich without this tune. Its just a bit dis-heartening I guess to spend $$ for no hp gain. My engine hardware is running at capacity.

you said it runs even richer now..

so how are you not ripped off?

same power, on more boost.

worse economy

worse cold starts.

worse tune with more shit on your rear bar.

tell me how you didn't get ripped off and waste $3K.

you would have gotter better tune with an SAFC on top of your piggyback thingy you had, by just cleaning up the RICHNESS you are complaining about.

    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
