Slow Boost Response, Plz Help

[Superdan]

Tried boost solenoid maintenance?

Checked all piping on BOV is ok?

As mentioned could also be actuator not holding boost properly.

ive plumbed the bov back to standard, wasnt leaking so il go back to venting it. Checked the cat out and was fine too, so gets them out of the elimination process. Still have to get the mechanic to check the actuator and solenoid.

im not so sure its the actuator cause I dont lose boost up top when im at full noise, once I eventually get to 15 psi it stays there

Replace the solenoid, will cost bugger all and is mostly likely the cause. If it doesnt fix it, then you can go searching. If you just "clean" the solenoid and don't replace it, you can never really rule it out as the source of the problem.

Have you checked the fuel pressure? When I first fitted my walbro intank pump I used normal fuel hose and it split within a month losing fuel pressure, the car took heaps longer to come onto boost as it was lean as (well over 17.1) but with no pinging and I didn't notice it unless flooring it as it just felt sluggish with normal driving!

It was checked by Blueboost with his wideband O2 sensor back in the day.

So could be blocked filter or dying fuel pump or hose as mine was?

we checked afr's last night, were in the 12/1 on wot, im doing the solienoid clean now as we speak, will let you know if it fixes the problem

[tonyv]

ok I cleaned out the boost solenoid, slightly better as I have never done it but im still having the slow boost response, this is doing my head in, lol
