Yeah yeah I know... I just knew I had other things that needed to be fixed too so I thought maybe those were causing the issue... They helped it but didn't fix it completely. SO now I know for sure. My new TBB shipped today... should have it monday.

man i always over analyze things too.. lol.. when i first installed my stage 2 chip it didnt have the thrust i thought it should. i didnt have a boost gauge either, i just noticed a hissing. but it was faster than my stock s4, so i just dealt with it.. then marc suggested checking it out when i told him it wasnt as fast as i thought.. check the easy, obvious things.. oh well .. glad you found it

Ok,
Just installed the SAMCO TBB and went for a drive... everything feels much better now so I decided to log again... Im still not getting as much boost as I think I should (doesn't the GIAC X tune give 17-18psi???)

Here is a new log:


What do you guys think?

Josh

P.S. This is a 3rd gear pull only.
