ScrappyFTW Posted August 7, 2013 Share Posted August 7, 2013 So I was reading around on different sites and read that 20psi is the max you can go on the stock turbo. The safe zone was anywhere between 12-16? Am I correct on this? I am just curious because I was planning on buying the Grimmspeed manual Boost Controller so I can bump my psi up a bit because right now it is only running about 7-8psi. Let me know your thoughts and what I should do. Thanks! Link to comment Share on other sites More sharing options...
wurkenman Posted August 7, 2013 Share Posted August 7, 2013 Put on a Grimmspeed EBCS and get a tune. If you woke up today, you have another chance to do it right. Link to comment Share on other sites More sharing options...
JermTheElf Posted August 7, 2013 Share Posted August 7, 2013 What? You're only running 7-8 psi? Should be 14 or so stock. Link to comment Share on other sites More sharing options...

Yes you can push it more, but it's really hard on the tiny squirrel in there. Link to comment Share on other sites More sharing options...
kzr750r1 Posted August 7, 2013 Share Posted August 7, 2013 ^This. Somthing else is wrong. Check all your vacuum lines are solid and if they look good tie wrap them anyway. Link to comment Share on other sites More sharing options...
ScrappyFTW Posted August 9, 2013 Author Share Posted August 9, 2013 I have a boost gauge and it's only showing 8psi and that's the max boost it goes to when on it really hard Link to comment Share on other sites More sharing options...
.Catalyst. Posted August 9, 2013 Share Posted August 9, 2013 Something is still wrong. You have a leak somewhere. One does not simply add a MBC and "turn up the wick" in these cars to 20psi First find your mechanical issue, then consider a tune and a 3port EBCS (if your tuner prefers that to the 2port EBCS from the factory).

ragman Posted August 9, 2013 Share Posted August 9, 2013 Stock boost levels should max around 12-13. Link to comment Share on other sites More sharing options...
spec.B Dream Posted August 9, 2013 Share Posted August 9, 2013 My guess is IAM is down near 0 and the ECU has disabled boost control. 7-8psi should be wastegate pressure on the stock turbo IIRC. Don't do any more full throttle pulls until you get your mechanical issue sorted. You don't need to buy a manual or electronic BCS, you need a mechanical fix, and maybe a tune, depending on what mods you have done. Link to comment Share on other sites More sharing options...
trhull Posted August 9, 2013 Share Posted August 9, 2013 I dont understand why anyone would use a MBC when the stock, open sourced, ECU has a good Electronic Boost Control functionality with good control strategies. You can buy an E-tune for around $150-250 to get some more power. Like EVERYONE above has already said, you have another problem, fix that then talk to a tuner about how to proceed with tuning your car. Link to comment Share on other sites More sharing options...
spec.B Dream Posted August 9, 2013 Share Posted August 9, 2013 MBCs have their place. They are great in hybrid setups to cap overboost in higher gears. Link to comment Share on other sites More sharing options...
