We received a call from a client regarding an issue with a tune on his newly acquired ZL1 Camaro. The car was already modified and sent on the way to the original owner with, lets just call it, a ‘rough’ tune. We can only assume this helped the original owner decide to part ways with the vehicle, and eventually brought Dynosty into the equation. We strapped the 4,000 mile car down to the rollers after evaluating the modifications listed on the original shops build sheet:
Pulley combination good for ~12psi, 1″ 7/8 longtube headers to a catback exhaust, cold air intake, aftermarket camshaft/valvetrain.
The thing that struck us; was the lack of any fueling to help keep this combination safe to romp around on the street. Stock ZL1 fuel pumps can see 650-700whp, ideally we like to see them upgraded as they tend to lose some pressure up top, but the stock injectors are another animal. At WOT we watched AFR climb to a scary 13.5:1 and decided to abort the run. How long exactly was the car being driven like this? We were unsure. We were positive that a call to our friends at Injector Dynamics would solve these issues.
In went a set of their proven ID850s and back on the rollers we went. After a few hours of fine tuning drivability and WOT, Hal finished the dyno session at an impressive 673Whp 652Tq. All on boost levels that could easily be increased with a simple pulley change, offering our client room to grow in the future! We love working with these LSX platforms, looking forward to an exciting spring!
Dynosty dyno tunes imports and domestics daily in Louisville, KY, and here is one example of a Dynosty calibrated stock computer. This 2014 Camaro SS 1LE came in for a routine dyno tune, seeking to improve drivability, improve fuel economy and safely tune for maximum horsepower. Mission accomplished!
