OK, I've searched and read hundreds of threads, but I think I'm more confused now than I was in the beginning.
I purchased a used 2006 Street Bob from a dealer. The previous owner had installed V&H Bigshots and the SE Stage 1, and nothing else. The bike pops and backfires like crazy, obviously it is still set at the factory "lean" settings. What do I need to do from here? I don't plan on changing anything else on the bike as far as those mods go. Do I need a SERT or PCIII or FuelPak, or can I just take it to the dealer or indy and have the ECM re-mapped? I don't want to spend a fortune on dyno and all that if it is not necessary.
I'm sort of in the same predicament as you are. Even though my 06 Dyna runs well with no ride-ability issues I do know it's lean. I could get a SERT and one of the latest O2 driven data acquisition units and then beat myself to death looking for the eth degree of perfection, but I don't have time for that, or the will. So, I've pretty much narrowed my choice down to the Terminal Velocity II.I also plan to geta similar unit by Remus for my 04 Buell.
It is your choice, but do is quick.That thing is running very lean. You could put the original football cleaner back on to richen it up a little until you get a tuner. I am going with the SERT. but I have heard that the Fuelpak and PCIII works as well. I just do not want a piggy back system.
Forgot to mention I didn't gravitate to theAlphn-n piggyback system by following the herd. The Alpha-n systems also tap into the TPS signal in a way that compensates for load. The TPS signal is sampled 500 times a second with the TVII , so it not only reads throttle position, but also the rate of opening to help calculate the appropriate amount of fuel offset. I also understand the system is very kind to your bike, meaning the plugs look perfect with no screwing around with dials.
I don't know anything much about electronics, just putting forth my reasoning based on the various sales pitches and independent test reports.
TV11 alpha n is for guys like me who aren't wrenches. It's simple,it evens out your AFR to the curve, adds fuel when needed-takes away when needed-adjusts for load,altitude,and humidity-it makes your "part time" cloosed loop system full time. AFR ranges between 12.5 to 13.7. several good tecks have told me it's the thingfor the new closed loop systems. I am amaised at how my 07 SB runs. It gets all the juce out of your 96-or 88-constantly self tunes as well. T-max is cool, but 3 times the money to have it done.

This is a very good system, and one I'll be installing on my bikedown the road.
i agree 100% with bigmohog. i know there is people who can do some this stuff them selfs.and that is cool.but to be on the safe side find a good turner. and have themput a pc3 or one of the other. you paid alot of money for your ride . have it done right and safe. and you will be super happy with what you did it's day and night diffence.you can't beat a great tune .
