What mods do you have to make 750hp?

I'd wager the issue is in your transmission tune.

What tranny would you use to replace that stock tranny?
You can have the stock HP70 built and tuned to handle it, or you can swap to the HP90. The 90 is MUCH stronger, but you'll need a new driveshaft as well.

If you're aiming for 900+hp, might as well call GForce or DSS and get the 9" rear end conversion as well because the stock read end won't hold that kind of power.

I live in Montana and am looking for atop notch tuner. Can you advise as i am having problems locating one. Willing to travel. Thanks
Idk how far you're willing to travel....There's MMX in Virginia, HHP in Delaware, Tapped Performance in DFW, Texas, BFNT in Cleveland, Ohio.

Everyone has their favorite and there are many many more. Yes some are a notch better than some others, but the ones I listed are all at the top of the ladder.
