i have a wrx 2002 with cold air intake greddy boost controller profec b spec 2 and a indivia turbo back exhaust sistem wanna know how to set the % on boost and gain and start boost for optimum performence the ecu cut my engine to fast need some help here plz

 

i have a 03 wrx with a full turbo back, and bov. i just put the spec 2 in aswell, i put mine in right next to the cup holder in the dash. enough small talk, here are the pirameters i put in to get about 11.5 psi in lo and 15.5 psi in high. note... turn the last boost mode on so you can see what boost your are running, and my settings are in psi not kapi or whatever

lo- gain 6%, set gain 105, waste gate 28%

hi- gain 8%, set gain 145, waste gate 44%


p.s. i dont thing my lo boost is set very well, i think the gain % is off, if any one else has pirameters send them along


keep truckin'... good stuff

 

just re-tunned my spec II and the low boost is as so near perfect its ridiculous and the high boost is just about perfect as well

lo- 12% gain 100 set gain 26% wastegate


hi- 10% gain 140 set gain 42% wastegate



keep truckin... good stuff

 

is your boost guage acurate the boost reading on the pro fec?

 

yeah it reads a spike with last boost display on, but other then that its acurate
