2015 Silverado Horsepower/Torque?

[Kla]

I have a 2015 Silverado LT Z71 with MBRP single 3" exhaust, K&N cold air intake and Performance Tuning Specialists Stage 2 module. Just wondered if anyone had similar mods and actually put their truck on a Dyno, and if so, what kinda numbers should I expect?

Low 300's for horsepower is my guess. Those plug in OBD2 things don't do as much as people think because they don't actually tune anything, they just modify signals to get a different outcome instead of manually changing tables to get more horsepower.

 

And the type of dyno can change the horsepower readings, so take the numbers you get with a grain of salt. Some dyno's could be 10-15hp different from each other.

Yeah, the plug in module doesn't do much. I have a Diablo tuner on order. Thanks for the response
