i know i know......... it was only 50 bucks on ebay though!

anyway i wasnt expecting much, but i figured why the hell not right? i programed my car, put the 93 oct. gas in and took it out. the results.........

car seems to run better, and a small gain on top end when floored.

not bad for 50 bucks, but please dont spend 300 on the programmer!

 

Used mine on my 97 about 10 years ago...not sure what I gained on paper but I felt a sotp gain for sure.

 

I used mine on my 98 LS1 6 years ago. It definitely corrected the speedometer and shift points after I added 3.73 gears. I boosted the A4's shift firmness 100% and it only made a difference under half throttle. But I was completely unimpressed with the "Powertune"! I couldn't really feel a sotp improvement. It only costed $350...... but oh well.
