ecu flash ?
I need to have my computer flashed/tuned I have a ecm from a truck with the 5.3 that I'm using to run my ls1. I know having it tuned on a dyno would be best but can't do that at this time. My question is who should I have flash it to get it close enough to running well by just giving them the motor specs? And roughly a the cost?
