Default boost problem

have got a 93 WRX when accelerating the boost comes on slightly then it sort of coughs a few times and full boost comes on the car then pulls fine. This doesnt happen every time though. Any ideas?

Are you running 98 RON (optimax) + a decent octance booster?, remember your car is mapped for Jap fuel 100 Ron, anything less will cause problems.

Make sure your running the right fuel before you look at anything else

Sounds like it did when my MAF failed. Try borrowing a good one to see if it is that

You're probably looking at £70 upwards for a second hand one (and be careful, as I've known a few people (including myself) who have bought a "duff" used MAF). And I think you'll pay around £200 for a new one (I recommend Grade-A, but anyone will do )
