I just put a Turbosmartxs MBC on my car because my stock setup would not limit the boost to 19psi it would go higher. But now with the MBC turned all the way down I have 19 psi limit in 1st and 2nd gear but in 3rd and 4th gear there is no limit. How can this be ? I can hit fuel cutoff in 1st also. Keith

You set the boost contoler on a long pull in 3rd gear. You will get less than your set pressure in first and second. Adjust it all the way out for minimum boost and then slowly adjust it up while testing by doing 3rd gear pulls. It should spike up to around 21 and drop to 19.5 or so by redline.

is it one of those turn knobs bc's? im pretty sure i know what ur talkign about. if it is, how would you adjust for different gears? isnt it one setting?

 

[keithsevo]

I already have the MBC at minimum setting. I can't turn it down any more. Keith

Is it one of the boost controlers on this page?

I have never heard of turbosmart until today.

Is there any active DSM group in your area that can look at your car and figure out what is wrong? This is getting hard to diagnose from behind a computer screen. 100% chance I could fix it in 5 min if you lived next door to me. Try out the philly DSM group http://herpetology.com/dsm/PhillyDSM.html and see if someone associated with them lives near you and can help you out face to face.

Later,

Keith

Sounds like it's installed backwards or at least wrongly.
