Hi all, I have just converted my manual NA BA ute into a turbo ute via, BA xr6t front cut.. Mods as follows- -4" dump and catless 4" exhaust -HDI cooler kit -60lb injectors -walbro pump As this is going in for a tune next week my tuner has advised me he has expierienced valve float above 11psi (on BA's) and has recommended vlave springs, is it worth me changing the cams at the same time to something like Crow Cams stage 2? or any other recommendations? other brands? pricing etc? any help appreciated!
