Labree HFC installed loosing psi on k03

[karmad]

Hey just had my labree HFC installed with labree dp to my APR 2.5 and was wondering if its a overkill for a K03. I will be going K04 in spring but lost some psi when boosting now, is this due to the HFC?

I also had put in some brk6e(coppers@ .28) and its winter here with avg temp is @ -10c and below are they ok to run or is it too cold of a range with the weather?

thnx and yes i searched

not sure about the spark plugs so i wont comment on that. i do think it is odd that since you installed the hfc, you are boosting less. when my cat ran away, spooling time dramatically decreased on my k03s, and i had a larger spike (12-13 psi on stock tuning). i would say check for any vacuum lines you may have knocked loose, damaged, or left disconnected during the install. check all your hoses, as well as the wastegate.

With no cat on my K03, big improvement on spool up time, also got a tiny bit more out of it, for a little longer too. Check for leaks is all i can suggest.

How many PSI did you lose?

Sounds more of a boost leak than anything. I have a labree HFC and 2.75" Cat Back Exhaust system on my flashed k03s. I hit ~22psi spike and when I had a leak I hit ~15psi spike. Full spool by ~3000RPMs.
