AP V2 stage 2 map ( boost issue)

[jed344]

i have a 04 wrx with turbo xs TBE, catless upipe, useing stage 2 91 octane map. i have acccesstuner race softwear and i did a data log today. 3rd gear 2-7k rpm and max boost i hit was 14.5. tried using HWG stage 2 map same max boost 14.5. any ideas why i cant get any higher boost? i have searched it was mid 70s today but i have never seen my guage go past 1bar it sits right about there.

Is the map your using only set to 1bar?? you should not really be going any higher then 1bar on stage 2 anyways. Are you running the stock turbo?

[jed344]

yes im using the stock turbo but says target boost on map is 16.5 -/+.7psi

Verify you have no preturbo exhaust leaks and boost leaks from the turbo compressor outlet to the throttlebody.The maybe try shortening the wastegate arm 1 turn at a time.This means shorten 1 full turn,log/check boost levels and if not hitting target boost do another full turn.If you do this before checking for exhaust leaks/boost leaks you will be chasing your tail..........

i think i know right were it is it if i have a leak lol ill try that and if it doesnt work ill try shortening the wastegate today

yea i think its a boost leak reasons are one at idle i run max 8 vacuum, used to overboost till i put on stock bov now i cant even hit target boost, noticed my spool time seemed to slow down. would those be reasons of boost leak?

[baller_v24]

it's probably the gasket at the bov?

[jed344]

thinking so it was kinda crappy and i didnt have anything to seal it up with so its just the gasket there to stop leaks. so im going to get a new gasket and seal it up

ok i fixed the boost leak but still im only running 9 vacuum is that normal?
