No need wasting money on software that will not get me anything better than stock. I know I can learn to use the software with time....I'm an engineer, gearhead, and have read numerous books/forums on ECU programming. I just havent done it yet.
Let's not consider that I would be able to change my gears, speed limits, and other paramters like that....I'm talking strictly about engine performance.
Thanks...

I can tell you this I have been tuning GM cars for as long as they had fuel injection, GM did not leave us much hidden power in these cars, More in the auto than the stick.
If you can find 10 hp your doing great, where the biggest differences show up are in the torque managment.
