I recently had some trouble with my rocket and had to contact Bob @ carptener racing. They did a up grade to the 270 kit. They did the conversion,dyno and tune in 2 days so I wouldn't have to make 2 trips. I am sorry that we got off on a wrong foot in the past. After seeing in person the way that he and all of his employees got the conversion done I was truly amazed. I would really like to thank the tech that wrenched on my rocket while it was there. He was calm and just **** good with a rocket. Thanks again for everything. Balls To The Wall!!!!!!!
