well, I just replace my MBC with a new OEM boost controll selinoid and I'm now hitting 25-26psi on my defi gauge. I'm pretty sure it's off because at dyno4mance my car was only hitting 17-18psi and my gauge was reading 21-22. I was having a fuel cut problem and now since I put everything back to stock(thanks nick. for helping my get the vaccum lines hooked back up right) my boost has went up to 25-26psi on my defi gauge so if it's still reading like it was down at dyno4mance. I should be right at 19-20psi... is that what the stage 0 map should be set at... my guess is that the MBC was some how affecting the way the car reads boost and I was getting fuel cut at 18-19 psi on his dyno... well anyways the car is definately pulling harder and feels alot better... what do you'll think.. do yall think my car is ok or do you think i'm magically some how hitting 25psi without an Xede flash.. thanks for any help..

Glad you got all the lines figured out.

Go into your boost table with xmap, and select the whole boost table, and move it down a few clicks. (about 6 or so) and see what that does for ya. Keep working until you hit the desired boost.

 

well, I was wondering what I should do since I'm hitting that much boost and not hitting fuel cut. my gauge has to be off... correct. I thought the factory boost cut was like 22psi... I think I'm gonna just take it easy.. I don't drive my car much, today was the first time in 2 weeks. I'll be back down at dyno4mance in a few weeks so I'll just wait till then and let andrew sort everything out. in the mean time I'm gonna do a little researching and see if my boost gauge is accurate or not... I don't like to have faulty things. it's just a problem waiting to happen.. thanks for the help..
