1st thread. I am taking my 08 heritage to a 103. I currently run reaper 525 cams, big shot exhaust rsd breather, the upgrade will include light port and polish on the heads .030 head gasket using stock 103 pistons. Was planning on shaving the heads to get to 9.5 compression. Question will the custom map I,m running now be a good starting point (powercommander3) say plus 10% across the board. Map was a download from feuling website, runs excellent now
should leave it alone but I'm gonna screw with it anyway

 

May be a starting point, but I'd call Fuel Moto to be sure.

I'd also say U'll for sure need a new map, more so since Ur doing Ur Heads.

U should flow a good increase in Air which will make her really lean.

thanks, kinda what I was thinking. power commander came from cyclesolutions last year. Will fuelmoto give tech support even though I bought somewhere else. hadn't heard of them when I purchased pc3

They might help Ya but thinking for them to actually send U a Map u need to purchase from them..

Don't hurt to call anyway, can't hurt as they can only say No..

I have a similar build, although my compression ratio is more like 10:1. I used TTS Master Tune and there's not a 10% difference between stock and current programming.
