should i send my ecu??
Okay ,so now i'm contemplating sending my ecu to LET for a tune+172mm pulley combo. I can't drive to LET myself because i'm overseas.and the only way to get a tune is to send them my ecu as per them.
did anyone try sending their ecu to LET?and do i need to send them a dyno run ,so that they can have a baseline to tune according to? or will it just be a pre-set tune they will flash?
