About 3 months ago on my 04 FLHTP I changed from Sampson 2 into 1 pipes back to factory headers and Sceaming Eagle older style pre epa slip on's.
I change due to a cracked pipe on the Sampsons. I like the sound and feel of the new exhaust better than the previous. I don't know what map had been installed previously with the 2 into 1's.
I am running a power commander 111 and down loaded the closest map for my present set up. I am stock except for pipes and a Screaming Eagle Air Cleaner also.
I accually gained a few hp and some tourque in the process. I don't know what tuning if any or even if the bike had the correct map in it with the Sampsons. So it might have been leaner? Although I would have thought it would have been richer before?
Before I changed systems I was getting 38.5 mpg average. Now I am getting 35 to 36 mpg average. Nothing else has changed. I ride solo and is still a full police package with all equipment in place including full windshield.
I weigh about 197 lbs. I don't wail on it much mostly just cruise.
Does that mpg sound close or about what most are getting?
