If anyone has any thoughts on this feel free to voice opinion. I had my bike tuned . I had the pcv already and I had the power vision. He tuned the bike with the pcv. When I got the tune from the pcv it only had 1 fuel table and 1 timing table . Is it possible he only tuned 1 cylinder? I have an 08 SG with s&s power tune duals thundercone mufflers mach 2 A/C Andrews 48h cams. Attached is the dyno sheet. The bike stumbled bad on take off after tuned it. So I imported the tune into the PV software and wrote it to the ecm. And did several A/T sessions and now the bike is smooth as butter. But I think I got took on the tune to start with. The numbers were as I thought they would be. But he had all kinds of excuses as to why he couldn't tune it better. Said the cam was too big for the engine. Anyway it runs much better than it did. After using the PV.

 

If you're going to post a gentleman's name and ask a public forum if he screwed up, I would suggest asking him your question privately. Personally I think that's very uncool.

However, the answer is if it only has one fuel and one timing table, the same changes are being applied to both cylinders as opposed to a fuel and spark map for each cylinder which that product is capable of. Dynojet calls it an Advanced map and the single table is the Basic.

 

I did ask him. If you read the post he had a bunch of excuses as to why it wasn't right.

 

I know nothing other than what it feels like when the bike is tuned well, but since you're soliciting feedback, I would say to go into your original post, eliminate the name of the tuner and replace with "I had my bike tuned and here are the problems I encountered..." along with the chart. It sure doesn't look like it was smoothed out at all and I imagine would be pretty herky jerky feeling.

I think if you did that you might get some good input from the real tuning gurus on this board.
