I have fiesta RST EFI has standard TURBO but chip 195, 701 injactors a good camshaft and PISTONS Forge and 1.1 bar of boost the problem is from a few days ago-the boost shows only 0.5 and i can boost no more because you start cutting where previously cuts(boost limit) if I add more from 1.1 the question is why im see only 0.5 bar of boost all of a sudden?

Sounds to me like the chip,actuator or boost control valve has snuffed it mate although I wouldn't know how to diagnose it have you tried disconnecting the battery to reset the ECU ? I would also try taking the chip out and putting it back in again could have wiggled loose?

it really look like chip, today i change the boost gauge but still shows 11psi it was 1.1bar i will reset the ecu but last sunday in 1/4 mile it runs good i drive with toyota GT and fiesta rs i win over them so if i reset and still have this problem what you think mate?

At 1.1 bar you are really close to the standard t2 limits anyway. But I would suggest that you either have a dodgy actuator spring or a boost leak of some kind. Have you checked all your boost hoses for tightness etc.

yes i check for leaks no leak if im right wehn you have a leak on the gauge shows is that right? it stays on 0.5 bars . pls tell me what is dodgy exactly im not that good as you guys in inglish im from malta
