Hi peeps just wanted to see if anyone had any ideas / experience, I've recently bought another scooby for the missis to smoke about in its an early wrx 93 import , it's had a few bits done to it, things I no for sure are blitz mushroom filter , bailey bov, turbo back japspeed exhaust, tdo5, and it has a polar performance chip I've discovered tonight, I've been told it has bigger injectors and walbro but can't confirm for sure.
So when I bought the car it had a dyno graph for 290 odd bhp @ scoobyclinic last month , but when I drove it I noticed it was boosting up to 1.4/1.5 bar ,and boost cuts almost every time. No boost controller ! So I've chucked a mbc/ bleed valve on it to just to wind it down,so now in 1/2 gear it's .8/.9 then from there on its spikes at 1.1 and in high gears still can hit the 1.4/5 bar . And all the while the boost needle constantly fluctuating up n down.
I'm thinking a new Adjustable actuator and Maybe a electric boost controller.
Any ideas appreciated

 

Oh and I forgot that atm it has Perrin equel length headers but I'm about to pull them off and go back to standard headers if that makes a difference
