While we offer power ratings past the factory options you can take comfort knowing our team has over 25 years perfecting Cummins tuning so you never need to worry about engine longevity, excessive heat or unsightly black smoke caused by inefficient tuning. Power gains vary based on Engine and Factory HP rating, generally speaking an additional 50 - 100hp and 100 - 250TQ is to be expected. Please call or email your engine serial number to use so we can let you know available options for your specific engine. Be weary of others offering a "one size fits all" tuner with preset power numbers, engines with lower power ratings can safely gain more than engines with higher factory ratings. Also some lower power engines utilize smaller turbo's and injectors which could limit power capabilities.
