Fluctuating boost
I had my car mapped two days ago (widetrack blob sti), the drive back after the map was fine, however I completed a 200 mile motorway journey today, and the boost is fluctuating wildly.
At first I thought it was a random fluctuation, but there does seem to be a pattern. The car will sit at 1 bar for a few seconds, boost to 1.2 bar, go back down to 1 bar, then boost to 1.4 bar, down to 1, up to 1.6, back down to 1 etc. The clutch isnt slipping as there is no corresponding sudden increase in revs, stopped at a service and I did not see any split pipes, no cel light, nothing. Have any members encountered a similar issue? I have installed a new dump valve gasket, and Im not sure if the dump valve is opening when this happens (still on oem recirc). Current mods are : billet 321t prodrive sports cat 2.5" exhaust, 800 cc injectors induction kit with k&N filter HRC 255 fuel pump. Any help would be greatfully appreciated:notworthy Car has been a bit more difficult to start lately, but this maybe a seperate issue? |
Have you tried cleaning the boost solenoid? I had the same problem, cleaned it out and all's fine now. Also if you search "boost" it brings up all sorts that might help you.
