383 Off to dyno/tune
Well tomorrow it's off to the Dyno and time to get this thing tuned. I had a well known F-body tuner send me a bin file for a base tune and it is prety good but the car is runing lean and has a strange misss at 3800-4100 RPMs. I sent the tuner at Carolina Auto Masters a Data Master file and he said that tuning should not be a problem so off I go. I am hoping for good things so wish me luck and if anyone wan't to take a stab at where I will be feel free. A quick list of the motor specs are 383 (10.7:1 static CR) Comp 306, AFR 195 Comp prted by More performance, LT4 prted intake, FMS 36# injectors, Holley 58mm TB, Stainless LT headers/No cats/Magna Flows, Meziere HD WP, and 1.6 comp Pro Mag R/R's.

Good luck!! I just had mine finished tuned yesterday. I also have FMS 36lb injectors but switched to Accel 26lb injectors. I still have plenty of fuel room in the tune with the 26lb.injectors. Post your numbers and graphs. I will be posting mine as soon as he gets his computer up and running again, it crashed today. Mine #'s were 440rwhp/410rwtq with the air fuel ratio at 12.4-12.7 to one and from 6500-7400rpm 11.8 to 1.
