Sounds like you'll need to run a CKP relearn.

why would it only affect it on speed and not rpm if it was a ckp?
would that directly affect the way the car reacts to rpm?

With factory tune the SES light will flash if the computer senses that you are doing damage to your cats.
But it would most likely do it all the time, not at certain speeds or RPM's.
Do you still have cats?
You need to get it tuned.

the very first time i started it it ran like **** misfiring wanting to stall really bad i let it run for probobly 15 secs then shut it off started it again and it fired right up just fine but then again i also used the ls1 camshaft so the valve events were exactly the same as the pcm was used to whats it doin?

thanks for the input you guys
