Smile '14 Silverado picks up 25-rwhp and 26 lb-ft of torque, tune only
Hennessey Performance recently sent us this dyno graph of a STOCK '14 Silverado. It has an L83 DI Gen V engine, and was tuned with HP Tuners. Made 296.89-rwhp and 315.94 lb-ft of torque stock and 321.79-rwhp and 342.65 lb-ft of torque after tuning.

Good numbers from tune only!! Can't wait to see exhaust, intake and tune numbers!!

I wish I could afford a $45,xxx 1/2ton truck and then void the warranty so I could make more power!

That's impressive. I'm predicting some really incredible turbo setups in the near future.

Wow, very nice. Hopefully you can still delete the DOD and VVT systems.

I wonder if anyone has made a DOD/VVT delete kit for these engines yet.

I'm impressed...nice gain over the curve. Now if the trucks were not so darn expensive right now.

Was that with 87 octance fuel?
