It was delivered quickly,had to update. After update it took 10 min's to program . I'm impressed with results. Not seeing mileage gain Yet, still playing with new H P. Trans shifts were greatly improved! A friend has a hemi, always dusted me for roll ons. Not now, asked what I did Told him, he is now purchaseing one for his truck Overall very happy. Product/ good Service/ good I have bought hypertec before and love the product First time user of auto anything, pain free!
good bang for the buck without giving up drivability
very clean appearance, easy to install, easy to set & adjust. performs well. minor mileage benefit-major performance benefit!with only the addition of a new k&n air filter and the edge-performance mode is like driving my 72 nova with a 400hp small block(a blast). there seems to be absolutely no down side for a relatively small initial investment.
