Hi there, i was just wondering if anyone has solved a problem of boost cutting out, or fuel.
i have put bigger nozzles on the injectors and ever since at just over 3000rpm in only 5th gear it cuts almost all power to the accerator pedal until i restart the engine then it goes back to normal. i have a BMC filter exhaust, egr bypass bigger piping and chip and it does give alot of boost with a small puff of smoke only briefly and revs free to 4500rpm never cut out before i fitted the bigger nozzles and why just in 5th gear??????.

many thanks..

Sounds like sticky turbo vanes or actuator, now with more fuel the boost goes too high and ecu trips into limp mode. Check vnt actuator for smooth full stroke under vacuum.
