My History
Raced and built imports, raced 70 440 Cuda, built LS1s
I had a local tune done on the car by a guy and it was good. Noticed increase HP and TQ. Not much change in shifting. Over all you could feel it in the seat. Also shut off DOD. Lost about 6 miles per gallon.
I decided I wanted to change the shifting up a little and shut off the rear cats. Which I did with and SCT X4 I bought online. It ran ok, shifted better. A little more TQ and a little less HP then the other tune. Over all I liked it.
After doing some research I contacted RDP Motorsport's about a custom tune. I told him the specs. He emailed it to me that night.
I programmed it up.. went for a test drive.. Loved the snappy throttle right off the bat.. Shifted perfect.. right when I wanted it to when driving in town.
Then I stabbed it.. Instead of hesitation and a lug down it JUMPED forward. Broke loose the tires in second gear, not just a chirp, spun them for a second! Cool but and not expected! It pulled like a freight train on the top! Smooth and steady. No I need some better tries.. and mine are not stock by any means.
My advice.. buy the tuner from them since they offer you a free tune as well!!!! AMAZING!!!
