I called FT today and spoke with Mike. He suggested the GT6152, even though I mentioned the 6131. He said it would spool up faster, and would work well with the stock converter. This was after giving him my full combo. He also suggested another chip, other than the Red's I have, since the reds I have work with alcohol injection. He suggested I go with a chip for 93 octaine, then upgrade the exhaust, then the turbo and alcohol injection, and then get the chip re-flashed to handle the alcohol. Said it would be a high 11 combo. Not sure why he suggested different turbo. I'm not familiar with how much experience these guys have with turbo's, so who knows. As for me, I've got the chip on the way, and will follow his suggestion of exhaust next. Thoughts?
