Dave, just a comment on your intake.....not a criticism but just some info.....we did a similar 90degree turn just upstream from the MAF and had some flat spots in the power curve....it seems that the darned thing is sensitive to turbulence and GM suggests 12" of straight air flow before the MAF sensor. If you see a similar symptom, that info might help you. We tried baffles, etc and even a programmable MAF. Car is looking nice.....you have a lot of work in it, time to enjoy the ride.
