3 bar map problems
 

We're using BRE 2.0 and the car has a b16 with pr3 and is built runnin 12psi.

Car works perfect until you make a hard run to redline and then I get a map sensor code and the car will stall and the a/f ratios get really lean. I just installed a 3 bar MSD map sensor. Once you restart the car it runs perfect again.
We've already tried another new map sensor.

Has anyone else had an weird problems with 3 bar sensors?
