I just installed a hks bov and dejon charge pipes with the MAS reloction flange. put it all on, adjusted my vacuum hoses to skuruc's dejon piping install thread. My problem is i boost a couple times normal and then it only starts boosting 3 psi. I am not tuned. thinking about getting one. I also dont have a block off plate. Help me out please.

 

You did a MAF relocate without a tune?

 

Either go back to your stock charge pipe, or get a tune immediately! You can not relocate the MAF without tunning for it.

 

does this mean i cant do my dejon cp w hks bov either? (planning on tuning after i do the cp n dp) i was planning on it soon... :/ this only happend bc he relocated the mas correct??? hhmmmmm might just get my synapse dp first..

 

i moved around a couple vacuum hoses and it runs fine and boosts normal now.

 

Ya but you should see your fuel trims. You wanna know what really wrong go get an interceptor

 

the problem came back. its still acting up.

 

tune it and your problem might be fixed

 

i have a 2010 cobalt ss t/c. i replaced the factory charge pipe w/ the dejon charge pipe kit w/ the hks bov. since then at random times, vehicle only puts out 3-4 psi... does anybody know what may cause this? if so... what do u suggest. thanks

 

yea its because you are blowing off metered air out the window.lol i started off that same way when i didnt no much but either get a tune and fix the maf or relocated and tune like most are doing when they run bov. until then if you still want to have the hks, t the hks into the top of the intake manifold and leave the stock bpv hooked up the same way. now you have two.
