When I put a home built duals on my old mander I did a power Commander with auto tune .
I did not want to be one of those that are tuning when the group stops .
My mander was running lean before adding the fuel controller and plugs were 100% perfect after . The old girl still runs good

I have the dobeck AFR plus it is very simple to use and you can make adjustments on the fly. I have a newer commander the uses the oxygen's sensors for anything below 6000 rpm so I can only adjust the afr above that. I really don't have any seat time with it yet so that's all I can really tell you about it for now.

I dont recall him having flashes for his BBK's that didnt require any further tuning. Last him and I spoke, the only way that happened was if your machine was on his dyno.

Sorry I would have thought all that was taken care of when he started flashing the ecm. Before that you needed a stand alone fuel system to run his big bore kits. So without his dyno guess he still can make the kits run.

Yeah he could make some tweaks.....seems like I recall him having a flash for like a slip on muffler or full exhaust maybe? But when it came to BBK, there was too many variables......what compression you chose, cams, intake, port/polish, etc. that would mean having way too many flashes and not worth him having a tune for every situation.

But it never hurts to call him and find out for sure?
