My boost is lousy
Little bit of background:
Evo VI GSR
Forge adjustable actuator (hardest spring)
Forge recirc DV
Decat zaust
Std airbox with HKS panel filter
Walbro uprated fuel pump
Put the ralliart on today, left the car running till the fans kicked in (urban myth?) then killed the ignition.
This evening once the temps had dropped outside I went for a spin.....no noticeable difference in power deliver and I am now boosting at 0.8bar. With my original ecu I could hit 1.1/2bar on a night like tonight. Do i need some form of boost controller? If so, do I really need 200quids worth of APEXI or HKS or would a dawes suffice? All I'm looking for is 1.3bar.
Thanks for any/all sugestions.
