Well after getting to the shop. I was told the Dynojet wasn't working and all they had was a Mustang Dyno . :(

Even though the Mustang Dyno read lower, its actually better for tuning. Soo...........

I could only get 7# of boost. Not the 10-12 I was hoping for. (Time for a smaller blower pulley)
And running really rich 11:1. I ended up with:

550.5 RWHP - 505 RWTQ - 7# Mustang Dyno

Nice numbers, your 1/4 mile time should definitely be lower then what it is though. Please tell me you have a 12 bolt rearend?

Nice numbers indeed...Also nice to see 2 other people in the So Ca area that are into LS1's.Seems the majority of the people that are into these motors are mid west or back east.Anyway maybe one or both of you guys could help me out here.Im looking to build an LS1 and put into an older car,but need any ideas of where a repuatble shop is here in So Ca where I can buy a used motor/trans setup and also who do you guys use for your parts and tuning?Ive been doing alot of searches on this site and have got alot of info down but thought I would bring this up here as well.

Was that all done with the stock ECM?

I tuned it with HPTuners, but still the stock PCM.
