Urgent Boost help needed!!!!
#1
Hi,
Can anyone help please?
Suddenly last night my car started to behave strangely. On acceleration the boost goes up normally to 1.4 bar but, instead of staying there like it normally does, it then wavers madly between 1.4 and 1.0. The feeling is like I'm on and off the gass repeatedly, and it does this all the way to the redline.
I have an HKS EVC3 boost controller and FCD which I've had on for about 6 months with no previous problems whatsoever.
I had an EGT gauge fitted this weekend and I've recently had the cat back on and off for the MOT. But it has been running fine this weekend, just started misbehaving after last nights hailstorm.
Thought it may be some form of overboost due tothe sudden temp drop, but even when boost is set to LOW (1.0 bar max) it does the same thing between 1.0 and 0.7bar
HELP ME SOMEONE PLEASE!!!
Cheers
Rich

Thanks for the reply Deep,
but the standard solenoid is disconnected due to running the HKS EVC3 (and it has been for the past 6 months), so it can't be that.
This is something that has come on VERY suddenly.
Cheers anyway though,
Rich

Ooops!
No it's not. Still doing it but not so much now.
Few other ideas have creeped in such as maybe my wastegate actuator spring is a bit weak, causing the wastegate to open erratically.
seems worse now in the higher gears.
Any ideas?

Check to make sure the boost hoses are secure as well so that boost isn't leaking.
Specifically, turbo outlet, intercooler inlet and intercooler exit to throttle body.
