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.

The problem is the piggy backs are not as reliable and often throw codes or go into limp home modes. They may be okay for daily use and a couple HPDE days, but if one is serious about tracking their 135/335 or 1M a true flash is the safer and more reliable way to go.
