Guys -

Any tune -- whether piggyback or flash -- can cause an engine to overheat depending on settings and use. It has nothing whatsoever to do with the mechanism used to change the stock tune.

Among flash tunes there is Cobb, GIAC and maybe a couple of others. Among piggybacks Burger Tuning's Juice Box and Vishnu Tuning's Procede -- both available with a number of different maps-- are available.

Depending on which map you choose, the hardware on the car (oil cooler, larger FMIC, downpipes, meth injection, etc.), the octane gas, and the use, they can produce lots of additional power and work very well.
