Hi all, hope you all had a good christmas.
recently put a new cat back exhaust on my r34 GTT and am wandering if it needs to be tuned up or anything like that, the car is pretty standard but i feel its using a little more fuel than it should.
Wanting to get a boost controller fitted but heard theyre quite pointless unless the ecu or power fc is upgraded or the old one remapped??? What psi can you run the rb25detneo at before things are needed to be upgraded??
Would love to get it up 350hp to 400hp but am not sure where to start???
In need of some new coilpacks, can you guys recomend any in particular, superspark, jjr, yellowjackets. Dont really want to be forking out $600
Any help will be great, thankyou.
