mazdaspeed 3 over boosting
So I have a 2010 mazdaspeed 3 I bought the k&n intake for it and when I put it on my car went from running 15psi to 25 psi with just the intake I know its not supposed to do that can anyone give me a reason as prolly why it did this or what I can do to get it back to 15psi?
could be the waste gate staying open or u have a big ass boost leak
I know from having a WRX a lot of mods on most modern boosted vehicles requires a retune to at least compensate for the airflow. K&N usually doesnt require this but I would think that any change to the intake could possibly cause the issue. Best thing, install the stock intake, reset your ECU, and see if its still there. If not, you have your answer.
you dumb shit, if the wastegate was stuck open it wouldnt boost at all. if he had a "big ass boost leak" it also wouldnt OVERBOOST.Originally Posted by hadouken
a k&n should make no difference on a MAF based car as far as the tune, it will compensate for the airflow. You need to check the wiring & vac hoses to the boost solenoid and the vac lines to the wastegate. if i had to guess id say the line was left off somewhere.
I put the factory intake back on and the car ran perfect the way it should Idk wht it is about the I take but to jump almost 10 pounds is outrageous for just a intake lol but thanks for the help huys
Should have been glad and ran that bitch at 25psi, lol. jk.

Check and make sure you didnt disconnect the wastegate, or anything from the factory boost control solenoid
