Engine - Drivetrain

Fair enough. I figured I'd put the bigger kit on there to see some possible gains and didn't think about it possibly running lean until now. I did some looking into ot some say it's the same but woth a different tuning others say it's different and will go lean.

i always use the correct top end parts. is there a reason you are not using the correct top end parts for the correct engine ?. can't answer your lean question ?, as i don't gamble on something i know nothing about..lol.

Hey guys about to do a 500 top end kit on a 2016 420. My question is will I need a fuel programmer or will it be fine without one and not run too lean? I've seen things online going both ways, it'll be fine without a programmer and it needs one or it'll run too lean. Any advice?

She’s all back together and I got the heat cycles done just need a chain FullSizeRender.MOV IMG_4134.MOV IMG_4138.MOV

You'd make a good professional PITA... maybe shade is right ?
