I have exhaust, uicp, cone filter, mbc and ams mail in flash. What is the max boost I can set the boost at now since I have a tune. It is set at 23psi now.

 

I'm curuious myself, im running a Greddy electronic controller and it peaks at 26.3.
No CEL and it does a good job of holding 19-20 at redline. Any input?

 

If an AMS tune, this is a question for them. Its best to not rely on internet info for something like this. Call or PM them, they will be happy to help you!

 

well, I turned the boost up to 25psi and cel came on with full throttle and partial throttle positions and reasons I cant explain. So I set it back to 23psi. I thought I would of been able to turn it up 1 or 2psi with no problem after the tune. How is it the ebc can be turned up so high with no cel.

 

I think it has to do with the fact that all mbc's experience boost creep to some extent. Ebc's can be setup to boost the same in every gear. In other words, your 25 psi may have been 27 psi in 4th and 5th.

 

I agree with this. We don't know what the fuel ratios in the tune were set too.

 

any up dates

 

These are really capable of handling that much boost? My STI was at 18.5. Kind of curious myself how it runs with your boost setting compared to stock boost?

The check engine light came on because of some funkiness with how MBC's work with our car. It is caused by the ecu seeing too much boost at partial throttle. It is not necessarily an indication that you are running too much boost.

That being said, i would personally keep the boost at what the shop tuned it at. Or at least check with them first before you adjust it. Depending on how aggressive your tune is, it could be very dangerous or not at all.
