Hey man I got a tuned ecu from u for a 99 gt with gt trans and gtp swap. My ecu has a tune for a 3.4 pulley 180 thermostat and fan runs after shut off. I want a stock gtp ecu with the trans tune for my gt trans and 180 thermostat. If possible could u do that. I just want better mpg's since I don't plan to upgrade anymore
