A MUST BUY!
If you are thinking of buying this product you need to do it. I waited wayyy to long, pondered over reviews and finally pulled the trigger. Dont waste your time with anything else. I turned off the AFM and torque management, 87 octane tune, raised driving idle by 100 rpms and park rpms by 50, with firm shifts. It now drives like the V8 beast I bought, not a Prius...a must have for your truck!
