So story begins when I'm installing my AEM intake, i was taking off the hoses from the stock boost solenoid when i pulled too hard and snapped a nipple. Pulled the trigger and bought a Cobb 3-port along with an AP. Installed the 3 port precisely with the following ports:

Port 1: Intake
Port 2: Wastegate
Port 3: UICP

Put my car on stage 2 93oct and went for a drive on the highway.

began highly accelerating, sports mode through all 6 gears and my peak PSI hit 10.82

thought something was wrong, checked all the hoses, they were still sitting tight with the new hoses and the old clamps on both ends.

Ran on the highway again and same exact result, peak 10.82 PSI.

my following Mods are

UR cat-back
Turbosmart Dualport BOV
AEM intake
Cobb 3 Port EBC

Any body have a clue what could possibly cause this?

i do plan on getting a pro-tune soon, once i get a stock evo intercooler and IC pipes, already have a UR test pipe sitting here. Just wanted to add it to stage 2 to make it drivable at least.

What do you mean by Port 3 - UICP? Port 3 should go to the compressor housing. Or is that what you meant? Also... did you use the new vac lines provided?

ralli_angel

yeah sorry, the compressor housing, its at the end of the UICP which is why i interpreted it that way lol

ralli_angel

yeah sorry, the compressor housing, its at the end of the UICP which is why i interpreted it that way lol and yeah used all new vac lines and kept the clamps

Did you double check your electrical connections at the ebc?

ralli_angel

Yeah I actually just unplugged it and plugged it back in now.

this morning, I put my car at stage 0 and took it on the highway, on 6th gear pull from 1.5k rpm to about 2.5k rpm I hit 23 PSI, so I don't think it's a connection issue at this point, I'm currently throwing it back to stage 2 91 oct and testing it out the same way to see if I reach those levels but it should peak at 21PSI with stage 2

.M.

So flashing stage 0 increased boost? That's weird. Anyway... be sure to report back.

ralli_angel

Yeah, still not sure what the issue is, did stage 2 91oct and could not get more than 10.3 PSI, went back to stage 0 and same, i did the same 6th gear pull and could not get more than 10.6 PSI this time

contacted Sean Ivey from Ivey tune and he said it sounded fishy as well and it cant be a boost leak.

probably a long shot but im going to swap my turbosmart BOV for the stock evo x BOV and run it this weekend

.M.

So now stage 0 is also putting out 10psi?

I'm betting your intake is the cause. Those Cobb OTS tunes aren't compatible with the aftermarket intakes and will throw your MAF scaling off. You would be better off getting a pro tune rather than using a OTS map.

See the notes for the maps requirements on cobbs site:

There's reasons why most of us don't use the AP and go for open source

Agreed, i had an AP at first and recently sold it in favor of open source with tactrix cable.
