    2015 mustang gt twin turbo won't idle

    Hey so I finally got my car together and fired it up today. The car starts, goes into high idle but instantly shuts off. I tried using the stock MAF tables then loaded a tune that a fellow member here modified for me as a base and both have the exact same results. Anyone have any idea in what this could be? I have uploaded my tune and the edited one (named base file). Thanks in advance

    3" is too small unless you are planning to stay under 5psi. Your MAF data is not any good for 3" pipe either.

    I have a very good TT tune for those cars - email me directly if you want a good base tune.

    I got it going I ended up taking (pi)36^2 and dividing that by the stock maf numbers and multiplying that into thr table it runs great now
