Boost leak, almost given up!

[Gubien]

I'm getting crazy of this ****! Jacked up the car and tighten the hose clamp, took power of ecu, did a tba og then drove around with some full rpm runs... Boost Is still where it used to be.

I'm pretty confident that its sealed now, the hoseclamp did look a bit fragile, so I replaced it...

One guy I know had a boost leak at his MAP sensor for a long time before he found it.
Watch that the hose clamps aren't too tight and perhaps might have split the hoses.
I take it you've been all over the boost system with your soapy solution?

LOL, I was thinking the same!

Just that the MAp sensor could be faulty(Slow)

I havent be over them all yet, cause I did not have any compressor, so tomorrow I will do it all over again to check for new faults, however, it seems like it knock alot less now!...
