Well as some of you know my dad has a gsx and i have a tsi awd both are 1995. Well i have a Greddy RS BOV on mine. He has an intake, MBC and boost gauge. We had his mbc st all the way up but never got more than 12psi. He has the stock bov aka the pos. Well today i said i'd let him use my rs bov which i have no idea why but was set all the way hard. He floored it and the boost gauge went up to 25psi, it started to creep up a little more and we hit a fuel cut. It had a ton of power at 20-25psi tho.

 

ya but doesnt sound safe. the motor will blow up if you do that again and again and it wont take much

 

You definetly need to turn that down. I wouldnt go anything over 17psi.

 

reason= stock bov cant hold pressure beyond 12psi due to plastic/rubber construction. Solution= 1g bov, wide band, brains.

 

Fuel system and new turbo on top of that to run 25 PSI safley
