Dynojet reads pretty low....I remembered that when my car was stock it registered only 192 rwhp. then when i got my Vortech SC installed same roller it registered only 276 rwhp w/ 7 lbs of boost. So he should be happy for putting up that much horsepower.

 

I got 310whp on a dynojet on a stock Vortech with a ACT PP and a test pipe.

 

Wow! I'm jealous....you must have a better engine than mine and also it might be your test pipe also. My car at that time still pretty much stock except for the SC and didn't got it tuned.

 

Well the numbers maybe on the low side but the car WOT feels good. As long as my AFR are safe throughout, I'm satisfied. After I get everything adjusted to eliminate my bogging/hesitation issue. Then I'll see if we can squeeze out some more power (what number should I be looking for?) It may mean a different tuner but at this point I'm happy.

The pulley I used was said to be from the previous owner to be 10psi, but on my boost gauge it reads ~9.6psi.

At the same dyno with 7psi with FMU I got 299rwhp. So a ~30whp increase isn't too bad, is it?

Any suggestions to squeeze more power or bogging issue is greatly appreciated.

 

Well just drove the car a little and notice my CEL went on. Went to the local Autozone and it pulled up P0170 and P1072 basically telling me I'm running too rich.

Hopefully I get that fixed and retuned and my bogging issue will be gone.

 

are you getting it tuned by an emanage certified tuner?

 

No, he's tuned other FI S2ks with the Emanage Ultimate but I don't think he's a certified tuner. How do I go about finding one? I didn't see it on their (Greddy's) website.

 

I too had mine tuned WOT but this last time I had it partial throttle tuned, IMO the second tune is a better way to go.
My ride feels stronger all the way thru the gears.....
I do have the AEM which of course makes a huge difference...

 

When I went in to get my tune (about 4 hours long), the tuner spent about 2 hours on my partial throttle tune alone on a dynojet, then he went for power pulls (WOT) for about an hour or so, and the car feels amazing, no bogging, no hesistaions, drives like factory besides the whirring.

Partial throttle tuning is more time consuming and may be expensive but makes the car feel so much better to drive and is well worth it, as far as the rich codes, doesn't the berk testpipe come with a CEL fix?

maybe you can call GReddy to find out (but theyre going out of business so who knows if they're still answering the phones). the only reason i know one is because they're a local shop and they have it posted on their website that their tuner is GReddy certified.
