What People Say About Us
Nick and the team at SDP are top notch! They've done an excellent job of getting my 7.3 back on the road and running like a champ. Nick is very personable and his knowledge of and enthusiasm for diesel engines shows in conversation. As long as SDP is around, my truck will never go to another shop. Keep up the good work guys!
I had a emissions delete, exhaust and programmer installed on my 2011 Dodge 3500. SDP is very professional and knowledgeable and mostly honest! I am very pleased with the work and would recommend anyone to go here for all your diesel work!!
2005 Ford 6.0. Nick and his crew are top notch. EGR delete, later a FICM replacement. High quality work, with fair prices. Would recommend them to anyone!
Excellent staff and outstanding diesel knowledge! Could not be happier with the results - Nick & Crew gave me a full walk-through before dropping off my truck and kept me updated throughout the job, to include providing me with other recommendations that I had not even considered. Extremely impressed and happy to have found my diesel spot. Stoked on my 7.3!
