Broke my vehicle while trying to upgrade certain parts on it. Did not offer to even fix their mistakes. The best part was the fact that they modified a vehicle that they had little knowledge of but did not share that fact until after they blew my engine! They even had the guts to charge me to put the original parts back on the car so I could get a new engine under warranty. Do not trust these guys! I'm not the only one out there who has had issues.
