I rarely if ever ask for help but,,,
I could used some guidance.. I have been working on this truck for years.. I paid a "performance shop" to just make it match what the Dodge Viper Truck would perform... The guy didn't have a clue but never informed me of such... Finally got the truck back, need to change the diff fluid "break in" two bolts hand tight holding the transmission crossmember, no nut holding the transmission the gears he installed in the rear diff Destroyed all driveshafts. fuel lines to small,,,,,ect..... Broke down and brought it to a different Performance shop to get the tune right, I purchased $3k+ from the tuning school but just couldn't figure it out.. the new performance shop. blew a radiator hose, then the blew the radiator, and replaced the hood latch handle in the cab... $3k..... they call and they cant get it to Idle.... I told them ... I drove it to your shop what do you mean.
after it sitting in my drive for 4 more years i have started tinkering with it .... I finally found where they enabled the MAF ... I don't have a MAF.. the turbo splits them in half..
Questions - Cylinder Airmass - Does it require modification due to forced injection? If so how?
Look at the injector data I have please.. I complied it years ago.. Seems ok. it runs and drives. stumbles WOT at 2.8-3.2k rpms ish. (If I remember correct back then I had a great deal of support from the tuning school, (we were fighting knock retard then) I finally got fed up and turned them almost off (hoping I would blow it up and all my problems would be solved)
Also the first Performance shop chose all the parts not me,, With what is listed in the the signature is it possible these components just dont work together??
Yes I realize its not the smoothest but if I am smoothing incorrect data from the start it is a waste of time. I have spent countless hours smoothing,,
The current rear axle gear ratio is 3.51 or something its a stock rear. the one I had built with 4.88's is too low for the trans.. Drive shaft rotation is insane..
I am attaching the latest tune,,, Having issues around 3K rpms.. I have done 11 gallons worth of pulls.
