I had a hks gt2530, 3inch system, high flow cat, split dump front pipe, ebc, power fc, pod. With this set up, it was making 212rwkw @15psi. I wanted to get up around the 270rwkw mark. So I did plenty of reading and decided going with a New hks gt2835 pro s bolt on kit.
My new mods are, gt2835 pro s, 550cc injectors, z32 afm, evc V ebc, 040 fuel pump, and i put a set of slitfire coils in just for good measures.
I thought I might get around 250 rwkw as here in tassie we have only got 95 ron pulp. But when i went to pick my car up and was told it made 222rwkw @15psi, 198rwkw @12psi, wtf! i was so pi$$ed off. just spent 5+ grand to get a 10rwkw increase. My tuner said its because we have shit fuel down here. Would 3 ron make that much difference? Anybody got any ideas why it would only make this amount of power?
thanks
