Re: 21 PSI on a GIAC Chip, this normal???? (Hapa88)
Doesn't sound right to me. I have GIAC V.4, and it peaks up to 17-18 briefly then settles to 15-16. Now mine is an AWD engine, yours is an AWW, but 20-21 then 18-19 seems a little high.
Call the place that installed it, and if they can't help, contact Garrett Lim (the guy behind GIAC) at http://www.giacusa.com
