Boost creep issue on 16g with o2 dump!? help! 21psi!

[2GEEZEY]

I need help with boost creep issue. Im running a evo 3 16g with a open dump, catless exhaust, stock mani. I have a 14b wastegate on it thats set to 15 psi because the WG that came on it was messed up. It creeps to 17-18 and if i go WOT in 2nd it sometimes hits 20-21. Same with 3rd. HELP!

Port the Turbine housing to open up the area where the exhaust gases enter the wastegate hole, or get some injectors and run 21psi.

I like the injector idea.

Lol actually im getting evo 560s this weekend. I hit fuel cut at like 18 ish.
But its not safe to run 20+ psi i thought?

I have a wally 255 and fuel labs afpr if that helps.

port the waste gate hole to the size of the flapper and bring the hole for the waste gate up more to the inlet.

its all in the tune and what gas you use. but you can get a really long way with a good tune. I have run 26psi on 92oct with zero knock and no meth. good intercooler and tune.

yeah everything else is done, i have a fmic, intake, etc. im saving up for a dsmlink, but going to pick up a safc this weekend off a buddy for pretty cheap.

I know that wont get my the best tune, but it should hold off until i get the link

No it's okay. As long as it doesn't get knock happy your total cylinder pressure should be fine for a stock HG and Bolts setup. But if you want to continue with it then swap them out.

like everyone said.. port out the wastegate hole; that should help you out for sure!

yeah ill probally do that this weekend. do you think evo 560s would be enough?
