[500SWMAGOPERATOR]

Will this programmer work with future performance upgrades such as high flow mass air sensors,intake manifolds,higher duration cam and larger cylinder heads?

@500SWMAGOPERATOR Out of the box no, you will need a custom tune that is designed to work with the mods you add to your car.

Hey I live in nj an I failed my 3 emmisions bc the DMV's computer wouldn't connect to my ecu. I got 3 not ready signals meaning the emmisions. I did get my car performanced tuned an I do have the diablo prediater. Is it a simple flash process back to stock? An I hear I have to drive it like 20-100 miles inorder from my ecu to relearn the stock tune?

If the custom tune was loaded on the flash device as a file then yes you technically should be able to select the return to stock file and return it to stock. That is of course if the person who tuned your car saved the stock tune file on there to begin with. But you should really just call the Diablosport tech line and do what they tell you. The number is 800-531-5484.

No, as long as you follow the instructions a tuner won't mess up your car.
