Reviews
"Great service. He gave me a discount when he didn't have to. This guy is fast and efficient. I'd suggest him to anyone!"
"Worked with me to clone my Body Control Module for a good price and then helped me troubleshoot further issues- all while I was in another state. Ended up needing some programming done to my ECM and that got me a back up and running. I appreciate it!!"
"Thanks Mr.Owner for always getting my computers done in a fast manner. I recommend!"
"I have nothing but praise and respect for this company. They have great customer service and they are always there when you need them. I ordered the 5.4 3V phaser lockout. My truck is now a beast. Great HP on the top end and low end. My truck started up on the first start and sounded great without any noises. I have to get used to the HP because it is very powerful. They did a amazing job with the tune that they are using. I highly recommend anyone who is second-guessing. Money well spent!! Thanks sincerely."
