O.k guys the Redback extractors and a Hi Flow Cat got fitted this morning.
Not much torque difference under 3,000rpm but after that it's much better.
Buying and fitting another members BPRD CAI that he had fittted to his BF 3V V8.
(may need some mods to fit my 4.0 Barra engine???)
I've decided i want to go for full dyno/
ECU tune on 98 fuel as you guys recommended.
Gotta wait about 2 months to get another day off work.
How much for full 98 dyno/
ECU tune with CAI already fitted???
