Just got my 99 34 GTT on the road after a long awaited compliancing and well already need some more power. At the moment its only got a 3 1/2 inch cat back exaust. Just looking at getting an SAFC II and a boost controller ( EVC, Profec B spec II, AVCR ?????) which is the best option??. What sort of power would i expect from these mods??? Any feedback on modding 34's would be appreciated.
Also does anyone know any good R34 tuners in Melbourne?
