i was also wondering on the subject of lpg systems, would it be advisable to chuck in some higher ratio roller rockers into an vx v6 with a factory lpg system, what ratio would you suggest and will it need retuning
I have been running 1.95 YT rockers since 2006 and around 100,000k's. Back then it was only FIT and YT who did rockers and YT were a better deal as they offered pushrods in the price while FIT has then nearly $200 extra on top. They were dearer as well. Also YT where just down the road for me, so i liked the added security if i needed anything. They are also excellent to deal with, but haven't offered anything new for the v6 scene.
Stock springs etc, no tune all this time. Wait till you do a few mods and then tune. Mace offer pushrods now as well, and what seems to be a better customer service, so they would be the best choice now for me personally. They have a good net presence, quick response, and are doing heaps for the v6 scene. I would go the mace 1.98's.
Mace, you guys have your own lpg v6 with these mods on anyway don't you ? Also what would you charge, for say a lpg tune inspection etc ?
