RRM Piggyback ECU install....
Well, here is another thumbs up on a great product by RRM. I just installed my v.2 Piggyback ECU and I am loving the performance! I bought it from another member on the forum and sent it to RRM to be reflashed with the latest image. I have very limited modifications on my 05 Lancer ES just axelback exhaust and K&N sri, I'm going to be getting headers and a down pipe and the lighted crank pulley here in the next week and we'll see how that helps with the performance with the piggy.
