High everyone I've HD this problem ever since I've owned this car. The cars running lean For the car to be able to run normal timing is advanced to 25degres. Otherwise when I'm on wot car will splutter its way to high revs then free up. If I put a boost controller on and have 10 pound boost under wot it backfires with flames. New plugs Good coil packs Rb20,turbo ? Glows red after a normal drive. Engine comp 1. 150 2. 140 .3 140 4. 140 5. 145 6. 140 Standard ecu standard injectors Only mods are front mount and dump pupr back exhaust And a walbro fuel pump 6 months old. What could this be ???

it was a massive boost leak hose was completely gone aha still slight hesitation sorting i now hopefully

and also i took the rod off the actuator and its runs smooth as f**k obviously no boost ? so what do u suggest there? i have put a afm and borrowed a cas still the same ?

yeah timing was done by a mechanic today. i have a feeling its running really rich possible afm maybe ?

okay guys fuel pressure is at 40psi when primed and while i rev it it climbs to 45 there are no boost leaks at all. and the more i advance the timing better it gets ?

hi everyone i am having a problem atm with my r33 gtst rb25det it has been a problem since i have owned the car even after i have swapped motors. when warm or cold as coming onto wot the car surges from 2000rpm to about 5000rpm then after that it completely frees up. its a bad surge and if i hold wot when it surges it back fires and sounds like there's a front fire ? standard boost well standard setup, has front mount. i have got new plugs gapped at .8 and have swapped coil packs no difference at all timing is at 15 degres and the more timing i give better it gets also has a new walbro hp fuel pump cant remember what models was good for 300 hp tho. but when car is running or fuel pump is primed the fuel line isnt hard hard i can push it half way in . any ideas on what it is guys all help much appreciated ??? thanks for reading
