Yes, that is what my car pulled today on it's initial run today, with Kooks LT's w/ cats, a lid and Borla c/b (3/4 open) and 3.73's. 295.6! Could that possibly be right??????? I assumed I was putting that down bone stock !!!!!

The only thing I'm thinking is that when I brought it in, I was throwing a 420,430 and 1130 SES code. I never got to talk to the guy when I went to pick up the car, but could that have been a real bad header leak that he fixed between the first and second run (330.8) ???? I read on here somewhere that those 3 codes were exhaust related and "shouldn't hurt performance" at all. I would say 35 rwhp is hurting performance no?

Only the two runs? The second looks good. A third would be nice to "average" them out.

Did he do any tuning? You could have been pig rich.

Seems like you should have more power. That is one sweet *** camaro you got there. Its my new wallpaper now( hope u dont mind)

I should have been more specific - I brought the car in for a tune, but also asked them to diagnose the codes I was throwing. So I figure I probably got the average 10HP from the tune - the rest must have been from a header leak that was resolved after the first run.

anyone care to confirm?

hugger - thanks for the compliments - please don't include "295HP" on that wallpaper

What did it run before the tune?

What codes did you throw?

that was my first time on the dyno, so 295 is what it pulled without the tune. At that time I was throwing 420,430 and 1133, catalyst efficiency below threshold bank 1, etc.

I guess the question I'm asking is this - was that just a fluke run on the first time or could whatever was causing those codes (header leak?) really have hurt my performance that much???

I think this would be a helpful thing for a lot of guys on here to know, especially guys like me who drive around with their SES light on and not getting it fixed because the codes are emissions related!!!!!!!!!!!!!!!

After my headers install i ran 3mph slower than before (107mph) because of the SES light.... I fixed that and i ran almost 112mph... So yes SES light could hurt performance by making the car run rich especially when you have an 02 sensor to be the problem. The Long Fuel Trims will be all over the place due to the bad 02 sensor or headers leak.

When the car is in LIMP MODE(SES light is on) The pcm will pull timing and add fuel, therefor causing a major loss in power. So that right there is where your loss in power was.

Dont worry man, ull get the power on up there once everything is sorted out. No hp numbers on wallpaper, just wicked ride

RWHP really doesn't matter with an auto. However, I'm sure the codes were hurting you.

2MuchRiceMakesMeSick

The first two are hurting you. I doubt the last one is

420 - Catalyst System Low Efficiency

430 - Catalyst System Low Efficiency Bank 2

1133 - HO2S Insufficient Switching Bank 1 Sensor 1

I hate to ask this question, but what does that mean?

WORM why you say RWHP on A$ dont matter?

I assume he is saying that because autos eat power...they run good at the track but they do not dyno well.
