Be careful purchasing this product. No tuning whatsoever can be done. This includes shift points too. I was wrongly advised and purchased this product. Luckily, you can do a software upgrade to flashpaq for $169. Only tire sizes, speedometer correction, fault diagnosis and basic options available with this product. The flashcal software is great though! After the upgrade, my truck driver smoother and shifts more crisply! Only a slight power increase, but definitely a more responsive drive.
