i'm sure this has been discused many times but... few days ago i got my AP and did the stage 2, 93 oct hw map. i drove around for a day and tried not to get on it WOT right away i took it easy. but i did some runs today and i'm only hitting 15.8-16psi at the end of 5 and 6th gears 2nd and 3rd i would get about 12.0-12.5psi and 4th i would see 13-14psi.

i don't understand why. Cobb map notes say that target is 17.5 +- but i'm not near that. is the ECU pulling back boost? should i just give it more time?

my mods are listed in my sig.

any help

Probably has a lot to do with the fact you have a front mount. You're going to blow up your engine running the stage 2 shelf map. Good luck.

I know i will be getting a protune this week... was thinking about the PDX custom map. But how would me having a front mount will blow up my motor. i could see how because of my front mount i'm not getting my boost...because of all the piping.

Having the front mount changes all the boost, fueling and timing properties. You're running a map designed for a top mount. I've seen a 05 wrx with a front mount running a stage 2 map. The baseline run was VERY lean.
