Well, I replaced the 350 with this
Blueprint 355 and used the stock TBI. I upgraded the fuel pump to a vortec fuel pump, FPR set @ 18 psi and 80lbs injectors. It runs pretty good but it ain't right. I have a tuner that says he can dyno tune it and get it right but I'm skeptical. I'm gonna let him have a shot at it, but if I'm not happy with it, eventually I'll just convert it to a carb and I will need the trans controller. I'm just thinking way ahead and wondering what a good controller would be.
