what does code p2074 mean?

what does code p2074 mean?

P2074-manifold Pressure/throttle Position Correlation
- High Flow/vacuum Leak

what does that mean?

It's an overboost code. Basically meaning you are boosting more than the pcm is wanting to see...too much air not enough fuel. Do you have a wga? Are you ptb-ing a lot?

im spiking 18 and dropping to 14 or 15........................stage 0

And that's why^ If I remember correctly...anything above 17 will throw it on s0. If you do the "tip mod" it will prevent s0 from seeing your boost and prevent from throwing the overboost code.

And Thats The Pink Line That Goes To The Upper Intercooler Pipe Right???

its a 2005...........
will it help if i put a bigger fuel pump.....????
would i be able to raise the boost at all????

Oh...it's an 2005? Nevermind then...you need to keep the tip lines in place then. The only real way to help get rid of it is to try the tip mod(poking holes in the lines near the tip sensor so the sensor doesn't see all the pressure) or to get some sort of staged upgrade.

A bigger fuel pump won't help illeviate an overboost situtation....raising the boost will only make it worse.

is it ok if i spike 18 and hold 14 or 15???
do you think stage 2 is a good deal???? i wanna stay stock turbo but i want 300hp...... what else can i get other than a stage 2 but in the same price range......????

I would start with 17 spike and 14-15 hold. In all honesty, I think s2 is one of the worse deals out there. You could get s2 injectors, a fuel controller(dtec,safc, etc.), wga(kinitecs,agp,etc.) fmic, exhaust, intake...all for that price...and probably then some.

i already got the intake(mopar)i got it from my friend for 50$$$$..... the agp wastegate for 50$$$ also....... and i got the motor mounts.....and the mopar bov.....
oh and good luck with your turbo upgrade......my friend has it @ 20psi....
