Very disappointed

September 12, 2013

Did a lot to install this unit including draining and removing fuel tank, replacing the cross-over fuel line, replacing the fuel line from tank to fuel injector port, removing fuel injector connectors, running the lines, etc., then putting everything back together again. THEN THE UNIT WOULD NOT PROGRAM. But Dennis Kirk honored their warranty. I replaced the unit with Vance & Hines Fuelpak which only requires removing the seat to install. It works fantastic, and was easy to program. I ride a 2003 Fatboy.

I wouldn't recommend this item to a friend.

Smart Purchase

April 16, 2012

It took about an hour to install in my 2007 Road Glide It made the bike much more responsive. It acelerates better, runs cooler, cruises better, and seems to get better fuel mileage.

I would recommend this item to a friend.

Great product!

March 7, 2010

I recently installed a pair of Rinehart slip-on mufflers and a K&N air filter combo on my '09 Super Glide, and I wanted to make sure my fuel/air mixture would be correct, especially up here in the high country (9K - 12K ft above sea level). This A/N product was easy to install, and makes my bike run great. It really woke my Hog up! Great product! Just plug it in and forget it.

I would recommend this item to a friend.

Value and Performance

January 1, 2010

I found that the Arlen Ness Big Shot has several nice key features for the money your spending. Its ease of use in basic injection tuning is one of its best features. If your expecting a race tuner this is not the one for you but if you are a doityourselfer like 99% of us out there you will enjoy this tuner.

I would recommend this item to a friend.
