Please see datalog from a couple 1/8mi passes this last summer. I have attached a couple of datalogs where the Calc MAP appears to dip or fall off during the run. It is a Gen2 longblock except Gen 1 cams and timing set. Intake cams are L&M Intake Only. Gen 1 Mustang exhaust cams. Turbo is a Summit S475 with 1.32 AR turbine side. Fuel is ID1050X injectors and dual 465lph pumps, Gen 1 6R80, Circle D converter, 2.73 rear gear to combat 4.17 first gear. Two relay transbrake (when used).
Pass 1- I noticed a MAF dip in 3rd gear which looked strange + MAP dip. 12psi boost
Pass 2- Just another file with a Calc MAP dip down track. 14psi boost
Please let me know if you have any suggestions. Thank you!
