Which Hobao Engine is that? Can you start by the color of the head, as well as the number of ports?

Oh hahaha, I got the 3 port version My LHS owner said he loved the 3 port due to it's fuel economy so I tried it out. Currently I have an OFNA 053 pipe and a Jammin JP-4. 053 for racing the mains and JP-4 for flat out performance. Mind you, the powerband is more aggressive with the JP-4. Hope this helps, cheers mate ~

Actually I was about to recommend you the JP-3 Well, for FEMCA I know it's illegal. You need an EFRA approved pipe for that. Ask the guys at your local track

yes, you must re-tune when you've changed to a different pipe/header.
