Hey Guys I have a question for the Stage 1 People I have a Stage 1 Internet map on my Exede and have a spike at 1.60 bar ( 23.2 psi ) and at the redline 1.46 bar ( 21.1 psi ) what do you guys think is that too much boost or is that ok ?

 

Well, if you are running 91 octane, I find that turning down the boost helps to keep the car more stable and the ECU won't reduce timing. If your car is running fine, enjoy the boost.

 

I am on 93 oct. and the car runs like an Animal

 

Are you running an MBC? 21 psi is pretty high at redline on 93 octane. Most of us are tapering to approx 18 psi at redline running Xedes. The midrange spike is fine, I'm assuming you have an Xedeflash otherwise you'd probably be hitting fuel cut.

 

I hit 24 psi on 91 at 3500 rpms but I have a custom tune and xede flash. My car pulls all the way to redline with no problems At 7000rpms I hit 18 PSI. Since you are 93 I think you will be fine at 21 PSI as long as you don't put costco gas in Also you should get an XEDE flash if you don't have one.

 

i see 23 psi all day long and that's at 7500 rpm, the car was tuned on 94 and has been for like 7 month now and no problems what so ever.
