GM's 2011-2014 Camaro ZL1 is one of GM's flagship sports cars. The 6.2L LS engine makes over 425 horsepower from the factory, and JMS was one of the first aftermarket tuners to start modifying this specialty vehicle. We have built and tuned numerous high horsepower 2010 and newer Camaro's for street, strip and open-track.


Our computer calibrations engineer, Monty Johnson is an expert in Chevy/GM ECU tuning and works directly with our customers to unleash all of the hidden power trapped in your stock electronics. You will expect to see typical gains of 25+ RWHP on un-modified cars with a basic 93 octane custom tune and SCT handheld programmer. Don't be fooled by other tuners claims! JMS has been in busineZL1 and custom tuning 5th Generation Camaros from the very beginning.
