Intake and SMBC
Well i just put the Cold Air Intake and SMBC on my car and wow!!!! You can tell a difference for sure. Though i thought i would just let people with the SMBC's know. If you look at the plastic piece where the SMBC plugged into on the sensor you will see that it has a very small hole!! VERY SMALL!!!! If you make it bigger it will Raise the boost on the Turbo, My Turbo was pushing 15 PSI well after the slight mod i just said i got it to push right at 26 PSI. Now i dont recommend running the Stock turbo that high.... Just Thought i would share what i knew. I will post some pics here soon.

You are pushing more air @ 26 psi than your software and maybe injectors can handle.
You boost like that on stock software you *will* go lean, and melt a piston. Then it's "big money engine out of the car time"

Made one of the ewww grinding type sound so i backed the SMBC down and it runs great!! no turbo lag at all!! 1'st gear pushes about 8-10 PSI then from 2'nd to 5'th pushed about 15-16 PSI.

Yea i didnt leave it at the 26 PSI. I turned it back down to its normal Boost. The SMBc just got rid of the slow spool time of the turbo.

i think when i made that hole bigger on the Sensor it changed that. But then again an Atmospheric BOV on a T-7 is supposed to make the Engine trip out and mine doesn't.

Your T7 has a deathwish.
So you enlarged the hole on the BPC sensor, not on the SMBC, right?

Correct on the BPC Sensor. Not the SMBC.

T7 is smart and would have cut it off eventually....hopefully before it killed the motor. Do you have any type of Data Logger or wideband on your car?

My car in stock trim would boost 15-17PSI with the SMBC and stock software.... 20+ is not expected for a stock car... that is a stage 4 boost level. Well we will see how it goes as he dials it in.

You ever hear those stories...you know, like Wangan Midnight, Herbie, and the like.......cars that defy all odds, seem to have a deathwish, yet at the same time refuse to die like a good little soldier.?

See the thing is i didn't mean to make the hole bigger on the BPC Sensor! The tip broke off when i pulled the hose off. Thats how i found out that it will push more boost. Honestly i don't know what has been done to the car. I bought it and i could be other 93 SE no problem. So maybe the owner before me did something to it, Hell i don't know. I just thought i would let everyone know what happened.
