figured id give it a shot here...

heres the deal, i have the injen intake and intercooler pipe kit w/stock bov and the AMS tbe w/test pipe. sometimes ill only hit a max of 10-11psi at wot and then sometimes itll kick back up to 18psi... and... sometimes boost will spike at 23-25psi!
does anyone have any ideas as to what might be causing these boost jumps???

thanks for your help

 

do you have a boost controller?

 

no boost controller, although im thinking that will fix the problem. i know its not a wastegate issue because i didnt have any problems until i installed the test pipe.

 

hmmmm i dont think a test pipe should cause that but i think a boost controller would eliminate your prob or narrow it down even further, and its an inexpensive and easy to use mod that everyone should have!

 

anyone experienced similar issues or think they might know whats going on? i could use some opinions. thanks

 

Forgive my ignorance, but what is an EE dualstage MBC? Also, I realize that it's none of my business, but why do you state that you have no boost controller, yet you include one in your modlist?

 

its a mbc i got from this guy in australia on ebay, ive used it on 3 diff cars now, its awesome. anyways, i just updated my mod list about an hr ago and wrote in the mbc because im installing it tomorrow.
