Yup I got an ls1. 91parkave's old set up except I'm repainting everything
I just got me a new MAF and intake and my own throttle body.
I'm guessing u mean the LED thing reading voltage? It was only temporary. I was going to use it but went with side mounted wiring instead of top.
Any more things I could do to improve it turbo? Ur advice on running ground straight to battery was spot on
