What is up guys, well... ive been having this boost creep problem basically since I installed my setup... Had it taken to a shop, re-preloaded the actuators.. still boost creep. Bought forge actuators with a 5Ib spring, still boost creep (althoug a bit less). Getting pretty tired of this problem :P Getting a hint of knock up top when it creeps as well.

I have an HKS EVC 6, i set target boost to 8psi (yes i configured it right, im a master at the EVC now after re-doing the setup about 100 times). At high rpm (5k+) I hit 9-9.5psi. My exhaust is APS 3.5" Downpipes into APS 2.5" Exhaust.

I am curious if there is a way to tune out my boost creep? Does more rich = less exhaust gasses? Or is it the opposite. Does it sound like its my exhaust setup? Too little backpressure = boost creep... but I highly doubt it since it seems a lot of people run the 2.5" with no problems... I dont think 2.5" is too big..

Anyways, let me know what you think, ive posted about this issue in the past but I feel I have a better grasp of it now, so I am able to make a post that makes some sense lol

I had terrible creep on my Talon. I hogged out the wastegate port and put on a larger flapper. Mine was internally gated, not sure about yours. Helped my problem a lot.

 

yea mines internal as well... it makes no sense tho, these gates should easily be able to get rid of the gasses to produce 8psi.... im clueless

 

use RPM offset to drop the gain in the higher rpm

 

Hmm please explain?

 

there is a RPM offset table
its in the directions
aim me and i can explain

 

In the utec directions?

 

evc6 manual
look for RPM based offset

you have to select it in a menu
then adjust it
ill look for the manual online and tell you
