I've had my ZFR on for about 3 weeks now. and I am having issues with it.

First, I cannot hit targeted boost and it is super laggy. Terminator has me at 27 psi, but in my logs its hitting 22 psi max and that is from 6000 RPM.

I did a boost leak test and found nothing. I have the Medium boost canister and its cranked all the way down.

Are there any other ideas?

 

Exhaust leak? Leaking bpv?

 

I am making a intake boost leak tester today when the parts get home. I was wondering if that might possibly be the problem.

 

oh I should note that my exhaust is much louder now that i put the ZFR on.

 

Did you setup the wastegate at all? could be that it's open a bit bypassing the exhaust turbine

 

It should be louder. Not only is the exhaust turbine larger, but the exhaust housing is larger too letting a lot more sound out now.

 

That's good to know for the future!

 

well i tightened it down all the way.

 

towards the canister?

 

No towards the 02 housing.

 

to tighten the wastegate you are shortening the rod so that the caniter has to push further to open it. Are you at the end of the rod?

 

lol are you kidding?

Yes its at the end of the rod. I thought it was the other way around. Full Race's EFR Diagram is what I followed

 

If you have it all the way at the end the wastegate can be open some even at idle...

 

ok heres what you do to get the new "starting" point put the nuts on opposite sides of the rod. one at the end one by the canister. push the wastegate shut by hand towards the canister. Bring the nut by the canister back untill it touches the wastegate and back it off a turn or 2 towards the canister for a bit of wastegate preload. bring the other nut in and tighten it down and that should help you out!

Do not go all the way in or go much more than 2 or 3 turns you will overboost!!

 

ok. Thanks for your help.

 

No prob now you'll really get to enjoy that ZFR!!

Prob want to send Term a new log too

 

yeah I feel like a moron cause he is like "I dont understand, this should be hitting 27 or 28 psi and its hitting 22"

I told him I tightened the wastegate lol.

 

Oh no problem i had the same problem and it took me forever to figure out and when i actually thought of this I was in bed and couldn't sleep all night because it was too late to get up and do it but I wanted to know if it would fix it.

Let me know how it works out for you

 

Also double check your waste gate control soleniod...my zfr came with a funky one...also my connecter was brittle and I was only boosting 23 psi instead of 26
