Glad you guys are happy. I always try and tell my guys it's not worth it to start threads like this. II has always treated us very well on any issues we have had even if it was not there issue.
A lot of guys do not search for that Gm service area. It's the same area that the dealer uses and they make the books from. It's not a DIY area that info is from Gm.
When I ran my GT4202R I had the 30% overs and twin cp3's. Made around 55 lbs of boost and egts were at 1500 thru the traps. The GT4094R with single cp3 and the same 30% overs were maxing out the 1700 egt at the 1/8 th hate to see what the 1/4 was.
