Hey Guys,

Running a

Highflow rb25 turbo with apexi SAFC computer running 1+ bar boost.
Full zaust and the ect..

So got the Walbro 550hp fuel pump thrugh it in last night.

But the car is still running like shit Idea's really lumpy,

and seems their is no fuel pumping through.

Maybe

Air Still in the Lines ?
Fuel pump Not right ?

Leaned out when fuel pump shat itself and melted a piston?

[ACTIV3]

nope Just stock pump couldnt hold the fuel, New one runs fine but when you put ur foot down abit it sturggles and cuts up around 5 /6 000 rpm.

Chyper also put some New tituam platuim tips,( shit) could be that also might need 2 get some NGK's ?

Been Told i might need a Fuel Reg??

[TJ]

Stock fuel reg should be able to keep up with your mods.

Maybe a spark issue.

Going on the Dyno today with new Fuel Pump lets hope it works if not might buy some Diff sparks

All Fixed just need a good tune!
