Not sure if my expectations are out of line or not. But I expected that I would not have decel pop after a tune. It is worse than it was before. I don't really care about the actual numbers, I just want a well running bike. Which I think it was better before. Can anyone interpret what is going on by the printout?

I had the SE AC, V&H BSS and SERT installed at delivery. Canned map for the first 1000 miles. Dyno'd today and I have worse decel pop. I'm thinking of having it redone by Trask Performance here locally in Phoenix depending on what you guys have to say.

Thanks

 

You probably need some custom dyno work to get rid of the pop. My son has a similar setup to you, and he has decel pop as well.

 

The # are not impressive, especially if it s popping on decel. Where is the AFR from the exhaust ? Cant tell much based on the Hp and Tq curves.

IMO if it seems to be worse and is popping they need to spend more time on the dyno to make it right

 

Interesting. I'm not going back to them. I have had all I can take from that dealer. I've heard good things about Trask and should have had it done there first. Guess I'll learn one of these days. My wallet is starting to hurt.

 

trask is good no doubt, might consider rev perf, ems it works amazingly. self tunes, and you can grow your motor into it without changing anything in the fuel set up. will do it for you. I'm telling you if you're going to do any work down the road, invest in this and you'll be money ahead and so happy, you won't be able to stand yourself, I know I am! my bike runs literally perfect, starts easier, throttle response is quicker, everything is better, just sayin'

 

Nothing on my sheet referencing AFR, so I don't know.

 

75HP/90TQ is about what you should expect from a tuned Stage I 96"er. However, it should not have any decel pop; ussually indicates a lean condition. Check head pipe connections and gaskets; check muffler to head pipe connection. If all are tight, it's the tune. You should not be able to make a well tuned TC pop on decel if you try. Particulalry with the SERT. I question the tuners experience and capability.

 

buy a tts mastertune and tune it yourself. its a great tool and it will teach you about efi.

its not hard either, plus you wont need to dyno your bike again buy the dealer!!

 

Most dealers do not have AFR sniffers. In my experiences.

 

what was the temperature when you had it tuned? What was the temperature when you rode it? Temperature will make a difference usually if its colder then when it was tuned it will run leaner
