I had a tune done a while back that was set for 23.5 PSI on an IX MR.

Current MODS include:
Megan Catback
Megan Cat delete
K&N Drop In
MBC set to 23.5 PSI Peak
Walboro 255.
I have no internal work done. The Tuner also uploaded a more aggressive MIVEC Map.

Is this dangerous for everyday driving to work? I usually gas it to full boost in the 3,000 rpm range to quickly cut through traffic in the open lanes. Or should I loser the PSI down to 20-21 PSI? Been having bad dreams with the engine creating some sort of problems.


Im starting to think that 23.5 psi is pushing the limits with the stock turbo and feel that Its just going to be putting in a lot of hot air. Any input?

 

tuned on 93 octane correct? if so you should be fine

 

also 23.5psi on a evo ix turbo is no where near pushing the limits stop worrying! people have this turbo pushing 30psi!

 

correct tuned to 93 octane. I have it tuned to 23.5, so everything should be A-ok?

 

Not a problem as long as your tune is intact. Boost On!!!

 

If the tune is good, it is safe,
I'm running 24psi on 92 octane with johnbradly tune, DD

 

I'm running 30psi daily with methanol. You have NOTHING to worry about.

 

As long as your tuner got the timing and fueling in line with the boost, you'll be fine.

If the tune is good you shouldn't have any problems.

 

You should be safe on 93 in a IX. You could log knock, just to play it safe. That way you'll know for sure.

 

I'm running 24.5 psi on 93 in my IX and no problems here.

 

I read in a magazine article written by Dave Buscher himself that Pumpgas is the new race gas. Meaning that he was able to push boost to 29/30psi on pump gas in an evo. So "it's all in the tune"

 

I run 24-25 psi on 91 octane

 

Pump Gas is not race gas. Yes, Dave Buschur tunes Evos to run 29-30# on 93 octane. But, I think that it's with the colder blowing HTA-35 turbo with a standalone, not on a stock 16G. In general, the IX Mivec can be tuned to run a couple more PSI than the Evo VIII's.

You are right. It is all in the tune. Bryan at GST can get stock ECU IX's to run safely on 91 octane at 26 PSI+. So, I guess that given the same car, he could tune it to 28# on 93 octane.

 

I run 23-24 on 93 runs great and 30 on race gas but I got cams w/springs retainers and head studs
