New Owner Of A R32 Gtr Vspec Ii

[GTR VspecII]

G'day everyone! I'm pretty new to the skyline scene. I recently had a 32 gtst for 4 months before selling it to purchase a 32 GTR... this car has been tuned in Japan by HKS and has turbos, ecu, exhaust etc all from HKS... my problem is that I think it will have been tuned to suit their octane petrol which is 103 or something....

so basically I need a re-tune so it's not running lean and I don't have to put octcane booster in the tank every week... anyone know if I can get this done in Vic?

I'm sure you'll get a much better response if you post this in the Victorian section of the forums.

how bad is the tune ? Is it pinging on 98 ?..Jap tunes tend to be on the rich side at times..however I am not so sure about ignition curves..
