A ses light does nothing power wise. You need to find the code that causing the ses light to go on. DO NOT get on your car until you find the code. Go up to autozone, they will scan it for free.

if you lost power and threw an SES code, then i'd hate to say it but you probably dammaged your engine. DO NOT beat on it untill you find out what the code is for.
how much boost are you running and on what octane? when you took it to the dyno did you have it tuned whie you were there or just a couple pulls to se what it made? what was your A/F ratio and timing on the pulls?

Flashing SES or Solid?

Check your belt recently?

Knock Sensor puts it into limp mode. You will not make much power if that's the case. (P0327/P0332)

I know the belt is tight. I running 93 right now, I've always ran at least 91. The ses light is solid. I only did 1 pull at the dyno, then we tried for 45min to read the codes with HP tune, and it would never read my VCM. I had a basic LS1 tune done. On that 1 run my A/F looked good. I think the ses light has been on ever since I go the basic tune done. Im really agrivated! I put on the SC and make less hp

Sitting around being pissed will get you nowhere. Go get the code scanned!

A SES light can definitly lose alot of hp on a FI car if it causes the car to go into limp mode.Have seen it a few times.

Do you have a Knock Sensor still? I was pulling 22degrees at idle when my KS went bad. It would pull off the line decent enough that I didnt think much of it..however after ~60mph the car was spent and lost a lot of power.

I'll get the codes read after work today. My car is a pig off the line
has surging at idle.

looks like a bad injector? "P0200 injector circuit open"
will hp tune tell me which one is bad, or clogged, or could it be a bad connection?
thanks for the help

when I get o2 crap it goes into limp mode and an 11:1 a/f at all times. It makes the car real rich and results in loss of power. Matter of fact the POS did it tonight I have a wide band in the car so as soon as the SES light comes out the gauge goes from 14.7 cruising to 11ish instantly

a code that has to deal with the injectors will put the car in limp mode. this is so you can drive the car to a place to fix the issue not drive it hard. this is why your seeing loss of power. as for which injector? probbly not just something in that circuit. efi live, auto tap and do some real time scans and see which circuit is having the issue. could be an injector, connector, pinched wire. good luck and hopefully its something easy or stupid
