I'm gonna be short and sweet hopefully.
I have a nicely built 351 in the truck. 9.5:1, 190cc heads, full exhaust, comp 35-255-5 cam, roller rockers, will have big dogs ported intake soon, 24lb injectors.
Stage 1 E4OD. 2200-2400 stall lockup converter, upgraded clutches, billet sunshell/gear, transgo tugger shift kit, and all new parts.
My issues are this, idle has been good for the most part but will surge on its own randomly, gets worse with AC/defrost on, will stall out when backing into parking spots or lightly touching throttle and releasing (started doing this before the engine build and trans). My BIGGEST issue after the rebuild is that the truck always wants to take off in second gear. Sometimes it'll hesitate from a stop then hit first and take off hard like its supposed to. Downshift feels funny at times, and it'll slip-shift here and there, other times it'll short shift and lock in OD before 40MPH. Those issues will correct after shutting the truck off and restarting, except the feeling like taking off in 2nd.
Truck runs great with no tune for the most part except the idle quirks. AFR's do what they're supposed to. I want to tune it with moates, but i need a good answer on what strategy I can use that'll be very close to JOG1. LHBL1? With what calibration? Or would it be best to go with MAF out of a 5.0 truck? (I have a maf 5.0 truck for parts). Any idea with the trans would be great. I've had the shop look at it 5 times and the trans tests good everytime and the warranty has 20k more miles. Does the tune have like a torque limiter for take off? This combo should just melt tires but the trans is super inconsistent.
Thank you, Joshua
