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.

    • Yeah this was also my suspicion, that pineapples exist to reinforce the OEM bushes because people CBF taking the subframe out to do it. Basically that pineapples and subframe lock collars perform the same intended task. The cup still bolts in under the bush/crush tube.. as to how it'll go I don't know. Two of the bushes at the back look mostly the right shape. The ones up front clearly have the impressions left by the pineapples. Time will tell whether this will work/make any difference. Ideally I would not want any lock collars or pineapples, I'd just want the bush to do the job of the bush. Time will tell if the car works correctly with only the poly bushes in the state they're in. Worth seeing, I think.  What panel work are you looking at? I'm shelving everything from the A pillar forward because it's shit/doesn't function and this was before I drove off at the track and then drove into somebody! A second hand Reo and brackets is $1000, which is just cray when Mr.Hammer turns this piece of metal in regular metal shape.. considering it needs to be drilled to be adapted to the GTR headlight brackets anyway... So I'm all for $0 instead of $2000 (new 34 GTR reo) for the same result lol.
    • I think he's already demonstrated that that's the way he's treating it post the paint jail release.
    • Yep that makes sense, thanks! I guess flogging these turbos in winter is more preferrable lol.
    • Bahahaha, bloody hell Greg. You've got bent and broken things, but instead, you're replacing perfectly good items. This story keeps getting more gregged!   Also, I'd 100% replace that reo if I were in your shoes, unless you panel beater is REALLY good. Even if you put another GTT one on there. Just because you've done so much nice body work lately, I'd say repair the body work fully  If it were more drift car spec, I'd be all "Hit it with a hammer and send it!"
    • There's a fair chance that my bushes are Nismo, because I'm reasonably sure that when asked the question (when putting the subframe into the car in ~2012) "What bushes do you want to run?", I'm pretty sure I would have answered "The stiff ones!". I had to put some silicone grease onto the GKTech inserts I jammed into them last week, because the bushes were quite resistant to having something jammed up their jacksies. So, I reckon you'll be best off doing Nismo + inserts. And, if I'd known you had PU bushes in the subframe AND PU pineapples, I perhaps would have said earlier that that's probably not a good idea. The pineapples are only intended to work with the stock type bushes, because those have a crush tube (which is what makes it end up looking like there is sloppy space in there - but doesn't, because the crush tube does make contact steel to steel) and the pineapples live in the space between the subframe's outer tube and the lower washer/bracket. But the PU bushes don't leave the space in the same way that the stock format ones do, and they do end up fighting for space. Order some bushes and collars and get to it.
