Re: lt1 help
your PCM (aka cpu) needs to be re-flashed with a tune to support whatever mods you did.
A mail order tune would be OK. Whoever you use would have a form you list what mods, tire size, gears etc. along with engine mods.
you either ship them your PCM or you can buy a cable where they send you the tune and you load it from a laptop.
search LT1 PCM tuners.
there is software you can get and DIY....although a skill set that needs to be learned vs the spinal tap version of turning everything up to "11"....
