Hi guys I have a little issue that I'm hoping I can get some help with. About a week ago, I extended the hose that connects my MBC so that I may have better access to it. Ever since I keep getting boost creep at high rpms.
I did a search about boost creep and found out the main source to be a leaky hose so I have gone back and gotten a better hose and new clamps I re installed the hose and MBC but I'm still getting creep at high rpms I will hit my peak at around 4k of 22lbs than taper like expected down but than at around 5k it shoots back up to 22.

I also since the install of the longer hose have installed a Megan racing Test pipe.

I'm looking to do another test this weekend, by uninstalling the MBC and letting the stock selonoid do its job, my guess is If the problem persists than my wastegate is faulty and may need replacement.

If you guys have any suggestions or have come across this and can help out I will much appreciate it.

Thanks in advance

 

Any one had this issue ?
