There's a guy up in Canada that ran circles around everyone with stock junk and Powerlogger on 23 PSI and a pedestrian 1.68 launch all day long. I recall he said something about the first 330 is everything and low gear tuning. He also said something about Buick owners love to struggle. Happy New...
A good set of heads. You'll need to upgrade the transmission. As soon as you throw boost at it, it'll start slipping on the 2-3 shift. Oh, I forgot to tell you you need deep pockets.
Powerlogger/tuning knowledge. If you're using Erics 5.7 chip it's usually rich in low gear fuel. Getting these cars through the first 330 is everything.
If you have a Scanmaster, post the numbers and I can likely tell you what it. About 90 minutes from you but can likely tell you what it is over the phone. DM me for my phone number.
