hi folks just bought a 1990 s2,its got scorpion exhaust,k+n,front mount intercooler,new engine
the ecu is chipped,but is only running 8psi
how do i turn the boost up and to what safe level
do i have to turn fuel pressure,
any help or advise

320 bhp

U TURN THE BOOST UP BE SHORTING THE ROD ON THE ACTUATOR (TURN IT) BUT WOULD RECOMEND IT TAKE IT AND GET IT TUNED ON A ROLLING ROAD THEY WILL DO IT ALL FOR YA SAVES U BLOWING YA ENGINE

zvhrst

same as 320 says,
or if ya want a bit more by a bleed valve and turn up to no more than 11-12 psi @most without a rollin road session

Don't whack it up blindly - best leave it as it is and get down to a tuners to get it done properly....

It will need setting up by a reputable tuner otherwise you risk loosing your pistons in a big molten mess of aluminium....

Best to find out what chip is in the ECU, this is the way to find out what boost the car could run and go to a tuner and have it set up properly.
Apart from that you could consider to mount a lambda sensor in the exhaust and wire up a air fuel gauge. Than you always know the mixture.

Cheers
