Anyone here run there tunes? if so what is your opignion?
I have been looking at all the vendors but precision efi really caught my eye with stock gauge flash and there knock system! I like that once a knock sequence is detect the ecu will automatically lower boost all the way to eco tune for safety
any reviews appreciated

There are people running it over on HCS and they seem to make great power. They have some real nice options that upgrade the gauge cluster as well.

He has his 2 Winders running their tunes as well as a dozen of his friends.
All I know is that the 14 Precision tuned 998's that he is familiar with have about 25,000 miles on them with no issues.

Just so you know the Gap platform reduces boost and pulls timing as well. You really can’t go wrong with any of the top tuners. Just do your homework and chose the one that’s right for you.Anyone here run there tunes? if so what is your opignion?
