I have a white evo with hks suction, hks exasht, and manual boost controller, and turbo timer. My question is why can i Hit 24 pounds of boost then drop to 22 pounds with these mods. Now let me tell u this i have never been on a dyno, never had any kind of tuning. The only thing that i can think of is that when i got my xm radio installed the installer mounted the brace for it and drilled through the wirng harness so i had to get that replaced but why that would do anything i dont know looking for some feed back. Now i can only hit that when it is cold outside, sense it is warmer now i hit like 21 or 20 pounds and hold it.


thanks Jason

 

Your not doing this on Pump gas right? (the 24 psi)

The Stock DV may have problems holding boost that high

Could be a leak in one of your connections.

 

My boost went up with the stock solenoid after installing an aftermarket exhaust.. Otherwise I'm not exactly sure what your asking..

 

Yes im running pump gas and my question is why are all of my friends hitting fuel cut at anything above 20 pounds of boost. no complaints here but i am ?ing it.

 

im running a 3inch catback, ecu flash, drop in filter and aftermarket bov. I'm hitting 25psi peak.

guess you're fine. and i'm running stock fuel pump and cali p!ss gas.

 

Did you set your Boost controller peak boost in a third or foruth gear WOT run?

If not than it may be spiking when your a WOT.

 

Where is your boost guage tapped? (Which vacuum line.)
