I know there are a few companies out there that offer chip tunes with flip switches, anyone used one? My car isn't redical, b cam, exhaust and intake. I'm adding a Vic efi manifold and I have a set of TF 170s that will go on at some point. I also spray a dry shot, going up to 175 for this year. I strapped it on the dyno when I bought it and AF was good on spray and motor, I just don't think the benefit of a tune would help that much. If anyone that has run one give me some thoughts. What companies are good, benefits and downsides. Thanks.
