on a stock 225 tt conv, my turbo should push little over 16 psi right?... my gauge says (14-14 and 1/2)...could bemy boost gauge calibrated incorectly?

 

No stock 225 is 10psi. Chipped 225 should run 17-18psi. Where is your boost gauge connected to?

 

14 psi is a little high for a stock 225. should be around 10-11

 

maybe he has a differnt n75

 

lol

 

My tt is stock except for my bov and cai and i push 14 to 15 in first and second, when I hit third it will hit 15 but then go down to 12.

 

your TT came on steroids... that definitely has to be the case

 

I wonder how lean your going when you hit 15psi, if your TT is stock because the stock program will only read 10psi that is it, nothing more. So something had to of been done to it if not your running lean most likely because the ECU is only throwing in enought fuel for 10psi and your running 15....i dunno just my thoughts. Unless your MAP is taking over then you may be ok, but I only thought the MAP took over when the MAF is disconnected? There was a guy earlier that had the same thing happeneing but we found out that he was hooked into a bad "boost" source, should be the FPR that your boost gauge is connected to, there are a few others but that one is the best and has the easiest axcess too.

 

you do remeber that my ecu sees 11psi and i run 20psi correct? The maf, map, and o2 will handle the boost to an extent.

 

Your ECU sees more than that becuase of your diode correct? If so then how did his "stock" TT get to 15psi with a BOV and intake?
