    I made the HUGH mistake of taking my truck to ATS diesel, After ATS was done my truck had zero turbo boost,They install a ATS turbo compressor, took it back to ATS they broke my turbo gauge and charged my $100 for a new gauge that they broke + $25 to install and said my truck was fine. took my truck to three other places and no one could find the problem. I found John at Performance Wise from a friend.He had the problem fixed and out the door in less than two hours. John and his crew are AWESOME. So run like Forrest Gump has never run before past ATS and down the street to Performance Wise. Best Damn move you ever made !!

    I have a 2002 dodge 24 valve cumming diesel and had replaced a injection pump and fuel pump. The problem returned after 1 day. I took my truck to DODGE (Johnson Auto Plaza) they couldn't fix it and DID NOT stand behind their work!
    I took it to PERFORMANCE WISE DIESEL of ARVADA, they fixed it and stood behind their work fully. These are truely the BEST Diesel Mechanics in the DENVER area and possibly the UNITED STATES.
    I would recomend them to anyone! Mechanics who truely are nice to deal with and know what they are talking about.
