I just installed the 11:1 Hess pistons in my p1000. I also have the HMF XL exhaust that will be in any day now. I also have the reduction boss IGR that will be in end of month. I already have the COPS tune installed. My question is, do i need to adjust the timing because of the higher compression, because stock is 10:1 and it seems id have to add 3-5 degrees of timing. ? So I can’t get intouch with ANYONE at cops ( COMPLETE OFF-ROAD POWERSPORTS) To help me out on this.
i talked to a HMF tech and he says the exhaust will definitively need tuned due to the higher compression, any advice or direction would be great. Thanks
