No question, I would buy the T-Max again and have... 90% of the problems people experience with this tuner come down to two things...
1. The module is defective in which case the vendor will replace at no cost within the three year warranty...
2. People either won't or can't read the 150 page manual for working with this tuner and follow directions...
I have three bikes with the T-Max tuner with only minor issues... Some we're my fault for not following directions, others the module was bad and was replaced no questions asked by the vendor... These things are not miricle workers, they are not the best thing since sliced bread, they don't have a magic wand that will "fix" your motorcycle with the click of a button on a lap top... They are a good tuner... There are others out there just as good, some say better but with all tuners, you need to read the manual, follow the directions and realize that the motor is not 100% tuned no matter what tuner you go with... The only guaranteed 100% tune is on a dyno with a "tuner" that knows what he's doing...
