You mean your SES light goes on when the car warms up?

It doesn't sound like a SC problem. But give us more details.

I think he means at start up when everything is cold it takes off like crazy but as soon as it warms up it has like a lag. Mine has done the same thing for a long time. For example if you are at a roll then punch it kind of bogs and then kicks in like you flipped a swicth and the warmer the car gets the longer it bogs.

How much boost are you seeing? Have you reprogramed the pcm ? At which point is it acting up on the log? I see you have a by-pass valve, what kind is it?

[2002 v6 camaro uncharged]

I see about an average to 8-8.5 Psi.

No I have not done any programming yet, don't know anyone with HP tuners for 2002 close to me. But it is on my Christmas list and I think its a done deal just have to open it on the 25TH :D . Its hard for me to tell where in the log it acts up, I have very little to no experience with tunning software. But, I think some where in the 50% throttle range is where it starts to bog.

During that run I did not have the by-pass valve. I removed it because the diaphram ripped but will replace with a blow-off valve soon.

(sorry to have hijacked this thread)

no ses light my car runs great cold but after it warms up it will bog when i start to accelerate, then like a switch was fliped power doubles

i don't think that is a supercharger problem. it sounds sensor related. (IMO) the suprecharger either works or doesn't and what you are describing does notfall into 'powerdyne slippage' category.

maybe try some of the other forums like gen tech. maybe get a free scan and see if you have any codes.

^ Like Grayman said. Do you have your MAFT screen on the throttle body?

It almost sound like the same problem I had when I took off the MAFT screen.

I took mine off and put it back on 3 times already. I have this mentality and still do that if I take it off, it would be better. I'm still debating with myself even today.
