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?

What don't you call Jerry and ask him all your questions? I sent my ECU to Jerry before I started any mods and had no issues.

You may not need to send your ECU at all.... they can send you a device to flash your own car with the tune.
