i have a 90 DA with T3/T4 set up. im using a greddy profec B spec II controller. it is kind of erratic im used to adjusting my gain and start boost and i know it says some set ups will never be completely consistent but i would like to get to and hold around 9.7-10.2 psi................the closest i can get is small spike to 10.3 and then hold 9.2 solid.

any advice on trying to maintain 10psi with greddy electronic boost controller, i know every set up is different, but any pointers with GAIN/START BOOST/LIMITER/TARGET BOOST settings will be appreciated!!

 

I found that the higher the gain is turned up, the more chance of having it creep. Turn the gain down and try to see if you can get it to climb and hold steady.

 

im getting it a lil more consistent, but exactly where i want it to be

i guess no one else has an opinion on this
