Jeeeesus.

So you are sitting at 1000rpm in 5th gear and it takes forever to boost.

Or are you sitting at 1000rpm in 1st gear and it takes forever to boost ?

How exactly would any harm come at 1000rpm in any gear ? catch a grip.

Fuck sake use a bit of common sense. Even without a rev counter any dummy could tell if you are sitting at 1000rpm, or 4000rpm.

Without proper details the question is meaningless.

If you are saying you are driving along at say 3000rpm in any gear and put your foot down and it takes forever to build boost, then it would make more sense.

but as you word it, it sounds like you are sitting in 5th gear at 1000rpm, so obviously it would take forever to boost. So no problem there.

If it is as laggy as you say, then blatantly obvious things to check would be for boost pipes leaking or undone. How much boost does it actually make when it does build ? Or dont you have a boost gauge ?
