Ok so I just got my tune a few days ago, and now for some reason my car is overboosting. The car is set to spike 25.5-26. The car does fine when I do a 1st gear pull but if I do it in any other gear the gauge will read 30psi. I can't understand why this is happening its really making me mad! What could it be. My mods are in my sig.

 

maybe your boost gauge is messed up.

 

if so turn it down a 1/4 of a turn and see wat happens wat is ur afr's reading ?

 

It looks like you've got an MBC. Turn down the boost to the target and watch AFRs.

Note: I'm not taking responsibility for you screwing this up.

 

Don't worry I'm not going to blame anyone if something happens to my car lol.

I have already played with the mbc a number of times and I still have the same result.

MBC do that under heavy load, better get AEM electronic boost controller you set the target and it stay's there no matter what.

 

That's what John from Jestr was telling me. I was thinking of getting the turbosmart ebc or the hks

 

I live by AEM don't know how those other one's stack up.

 

You might want to have JESTR take a look at it. He is an awesome tuner by the way..

 

stupid remark, I was just reading up some info on MBCs and AMS says that the X does not do well with the MBC, they recommend using a boost pill? maybe that could be it.
