Its from 0-20%. How ever, I believe with the DynoJet Power Commander 5 with the autotune module (comes with wide band O2 sensors) you can get past that block.
awesome. Just ordered and will install on Wednesday thanks for the info
i installed the auto tune along with my dyno jen mod , and to my suprize it held me back , some info i learned that even you un plug the stock 0 2 censors , the moto still trys to make adjustments to the bike because the can not be read , and at same time auto tune is making adjustments with new wide band censors , it was a mess , sent my dyna jet back and installed ejk and it works alot better , since i have snorkeled my moto it is getting alot more air flow ejk chip is able to keep up with the demand , runs great ,
