Almost There, New Symptoms. Won't Boost All The Way
Okay. Last week I had an Idle problem. 0507, found out I had a intake leak under the intake manifold for the bypass valve or whatever. Same goes for the Intercooler Piping. Got that fixed. Car idles fine, no issues there.
Now I can't go past .7 bars of boost. I checked my wastegate and the vacuum line is still on pretty tight and the setting hasn't been changed on the wastegate itself. It just won't boost past .7 bars whereas it should be closer to 1.2-1.3.
This all happened when under hard acceleration. It cause the vacuum line to pop off or something under the intake manifold. I fixed that and still can't boost past .7 bars. I thought it was limp mode so I disconnected the battery for about 30 mins and still nothing. Its a nice steady climb to .7 bars, about .8 bar spike as soon as I let off the gas. Does this for all the gears besides 1st.
I'm running the EVO Wastegate, Forge Diverter Valves. Both fairly knew with only a few thousand on both. Got both this year.
HELP!

Well no. This all happened (boosting only .7, idling rough) at the same time after a hard acceleration. It started having boosting problems same time i had an air leak in the intake.

No. Nothing else was changed. Just reattached the popped line back into where it belong. Nothing else was done.

The shop didn't know how to do a pressure test... Go figure.
Anyway, I need to find that thread so I can go out and make my own or something.

I guess i'll give the battery reset one more try. I'll just leave it disconnected for the whole day and attach it tomorrow and see what happens.
As far as I know ECU's cant be reset unless I rewrite it so we'll see. If I still can't boost past .7 bars I'll assume is a boost leak.
If it is indeed a boost leak that only appears under pressure, where would I look. Diverter valves, wastegate, f-hose... anything else?
