i have an lsvtec turbo b16 head with tial waste gate and w/ a 6psi spring in the WG and a profec b boost controller.....before i did the head swap i had no boost creep at all....now it is boost creepin to like 15psi with the boost controller off which should be at wastegate boost (6psi)....even when i set the boost controller on low boost and turn it all the way down it still boosts 15psi.... so i rerouted the vacum lines to bypass the profec b as if it was not there and it still creeps 10psi on wastegate boost w/ a 6psi spring.... help

 

get better wastgate or small diameter exhaust.

That Tial gate is fine...there has to be a reason...have you checked all of your vacuum lines...are they all hooked up correctly? have you examined the wastegate itself?

Khoi

 

yeah , consider gettin rid of that junky tial .....................not , thats one of the best wastegates on the market , double check the vaccum lines

 

what exhaust manifold are you using?

 

hes using a ss chrome , equal length tubular , the wierd thing is the car didnt have boost creep until he installed the vtec head , i think its just a vaccum line problem , but lets us know what you think , thanks

 

yeha what mase said.

if you have a 3 inch dp it can cause you to creep, if you have open dp it can cause you to creep, and if your vac lines go all the way to the intake mani or to the throttlebody area it can cause you to creep.

 

well he doesnt have a 3in dp , or an open dp , so its obviously the one of the other situations , thanks

 

thanks rob.... ok heres the deal....i checked all vacum lines and completely bypassed the profec b and i swapped out WG to one of my friends delta gates and it stopped goin to 15psi...now it still creeps to 10psi which is where i want it but it would still be nice to know why its doing this thanks for all feedback

 

ok **** everything ive decided that i like alot of boost and i dont care if it scaters but if you have anymore sug. let me know.....until then drivin like its stolen.. thanks

 

another thing is....i have a dump tube that is ran down and out my driverside bumper......i am about to take it off and see if it fixes anything.....any more sug??

 

after removing the dump long *** dump tube the car no longer boost creeps...now im goin to hook the profec b up again and see if anything changes...

 

wow, exactly how long was the dump? any pics?

 

i do have pics but not on here right now i will post some but its about 2 1/2 to 3 ft long....

 

actually it still creeps 10psi which is no big deal because thats ideal boost for low boost....no pics of dump tube right now bc camera is fucked up...but i will see what i can do about pics thanks
