Genuine people that know how to tune and modify mopar vehicles to optimal performance. Main guy Sergio is dope af, had many poor experiences in the past with dealerships and shops but Sergio always gave me peace of mind that my vehicle was in good hands and that any problem or issue due to any modification would be taken care on their end.

I can't say enough good things about the team over here at Definitive Performance, I had another mopar performance shop in the IE that I paid about 10k for a build and they completely butchered it . First day was stuck in limp mode towed it back and forth 5-10 times they kept telling me they don't know what the noise is and basically told me to F off it was crazyyy . Luckily about a year and some change later I finally found definitive performance and they took my car in with open arms knowing they're gunna have to fix some shops mess . Not only do they have great customer service skills here but Sergio really is a good guy and that's hard to find in a mechanic/performance shop now a days . On top of that they have the best prices around they don't over charge on anything if anything they will gladly take a loss to make a customer happy and they know exactly what they're doing . Thank you again definitive can't say it enough car is running amazing now .. top notch tuning from the joint efforts of spankintime and the team at definitive !
