Talk is cheap! Spouting off about how much horsepower or torque your combination produces is easy and is often inflated when the crew gathers. At Hulten Speed Sports, our proof is in the pudding! (aka Dyno Sheets!)

Check out some of our recent Dyno Results from tuning enhancements to full out Sinister performance package installations!


* Items such as air intake, exhaust systems, ignition systems, fuel quality are but a few factors that affect performance levels.   

Give us a call at 518-568-7669 to schedule a Dyno tune or performance build!
