Definately don't waste your money on diablo! It's locked up tight and like Trying to tune your truck with a Nintendo. Hp tuners is far more advanced and a better system. Well worth the money plus it's good for many other platforms.

Swap the drivetrain and suspension while you’re at it.Just ask anyone who is a horsepower junkie but not independently wealthy.I know my 6600lb.slug is at its limit just from a simple blower and tune. But ive been pouring/dumping money into a vette ,but I’ve seem the drivetrain on my truck and it’s puny,and overrated.B1F2F89E-6890-4AED-82F0-DE4F8859E940.jpeg80D1F392-F4A4-49D1-8BFA-FA346C17C344.jpeg8DE5C621-1CCE-4FA9-BFE2-D441B2CE3A6A.jpeg

Thats the issue, you have to keep emailing people every time you want to make a simple change. It gets old fast , I know I used to do it.
And HP tuner is far superior for tuning 8 speeds.

Yes you have to use the trucks FED ( front accessory drive set-up) you also need to swap to the trucks oil pan and oil pick-up tube,and check the back end of the crank to make sure it has the right pilot set-up to take whatever convertor you're using.
Message Brandon-W as he's did the SRT swap,there's a few other guys who've also done the swap to like Johnny *** Whelan (sp??),but i forget Johnny's user name on here.
