Re: GM Performance ECU - tunable for 33" tires?
What trans are you going to use? Which LS engine?
On my auto LS swaps the tuner could tune the shift points as I liked. I like and use Speartech or Howell harness and ecm for the base tune. Nothing against PSI I'm sure they can help in the same way. |
