You cant tell properly in video, but it pops like mas

when gt turbo ran like a bag of poo it was because i had blown the fuse for map sensor relay or something similar when i was wiring up a gauge.

it backfired and would barely run,and wouldnt rev up at all

do check ure fuses ,easy to do and worth a quick look

[Hawwy]

Which fuse would map sensor fuse be

[mikey4410]

check all ure fuses mate,under dash and in engine bay

[Hawwy]

Nah all fuses are okay

Hows the car drive,does it rev up ok,boost ok ?

Check the vacuum line from the map to. Could be split which causes alot of probs. caught alot of people out many times

After a drive it was popping while driving easy so took it for a nice Run then seems okay, lets see what it does tomorrow morning when its cold

Have you checked the spark plugs?

[grum-glanza]

it sounds nice it could be a injector not spraying right maybe a little bit too much fuel going in and not been burned if its on a emanage or other mappable ecu get the map checked to see is everything ok same with fuel presser regulators if any

[Hawwy]

Its not doing it now after a run

[Hawwy]

Doing this stuff again
