You really can't just strap a T70 to an OBD1 5.7 LT1 and expect it to work......
You need some type of fuel management, how many PSI is your wastegate...?
www.google.com, Highly recommended.

Maybe I missed the memo, but isn't 12# a HUGE amount for a stock LT1.....?
5 PSI is a 'healthy' amount on stock internals on my truck, it may be able to take 6-8 with a good tune, but big displacement motors NA usually need decent work for that kind of pressure unless I'm totally wrong?
You are probably detonating like a mother fucker.

You have a HUGE amount of research you need to do... This is not the kind of thing you can just hop on a forum and hope for an answer on honestly...

You're probably running too much timing, too much boost, too much gap, not enough injector and fuel pump...
What are you doing for computer? Stock 1bar MAP? Do you have a wideband on the car? Where is your AFR at?
If you really just slapped a turbo on this thing with 15psi... you should seriously consider giving the car to someone who can help you out before you blow something up.

Wastegate should just need a spring to lower the boost levels. Kinda confusing they would send a smaller gate with more boost though 
The bigger injectors will help, but you'll need to pull the plugs still (heard it's a bitch on lt motors) to re-gap them, and do much, much, more. STS sounds like they give about as much info as the 3800 vendors. You pretty much have to use the forums and help from others to figure out what you need to do. GL bud!

congrats on making the kit...seems like you have the mechanical portion down pat.
you definetely need injectors
possibly an aftermarket MAF
you are going to need a fuel pump as well.
as far as tuning on lt1s...

is what i used to use.
you need to turn the boost down to 7-8psi also.
any mods down to the car at all? exhaust?
what kind of turbo are you using? STS has a 'custom' housing to help with low-rpm spooling.
