I had a great deal on buying my 2015 Silverado LT. It’s not what I wanted (V8, leather, 4WD, etc,) but I’m going to make it work! It’s a beautiful color and I added some black 20” rims and also painted the bowtie black. I have a few more mods I want to do with the lights and adding a backup camera, BUT what I want most is HP!!! I called the local speed shop and they told me there’s really nothing out there for the 4.3L and I wouldn’t be able to notice the small increase with a Cold Air Intke, Exhausts or programming..... Is this true? I mean a few extra (10-15) for each of those mods seems like it would add up? Can anyone give me some advice to get more HP without dropping the obvious V8 I’d love to have to begin with..... Thanks so much in advance! TomBrady80

Does anyone know the real reason for the delay of the release of whipple supercharger for 2019 GMC AT4 6.2? Also has anyone heard when available? I can not get straight answers. I have been told a few different things like this Sierra has new computer from 2018. The air filter is on opposite side than last design so the redesign is taking longer. I ordered my AT4 2 weeks ago and wanted to time it to have it all to install when truck arrives. Not looking good atm. Any info helps. Thanks!

asking for recommendations for bolt-ons to give more power to my 1993 silverado 2500. Going to start using it to tow a travel trailer. It already has the factory tow package. It's a 5.7L [350] V-8. I've already upgraded the exhaust; thinking headers and a cold-air intake . . . any other suggestions?

I drive a 2015 GMC Sierra 1500 30k miles... I have a 2.5 lift with 20X10 hostiles with 33in tires and Cold air intake, looking for some more power and no more throttle lag. I am stuck between Diablo I3 and superchips F5 flashpaq. Does anyone have any insight or opinions on which tuner being better than the other. Appreciate all comments!!

Hey guys I’m new to the forum as well the brand. I recently just bought a 2019 custom trail boss which only offers the 5.3. I wanted the 6.2 but that came with only the higher trims. I’m familiar with the 5.7 hemi and I’m kinda down about the 355 horsepower/ 383 torque compared to my hemi that I traded. What can I do exactly to get more power to the engine?

By Zane Merva Executive Editor, GM-Trucks.com 6/18/2014 General Motors has released the final engine power figures for the up coming 2015 Chevrolet Colorado and GMC Canyon. The standard 2.5L four-cylinder engine will produce 200-horsepower and 191 ft-lb of torque while the optional 3.6L six-cylinder engine will be rated at 305-horsepower and 269 ft-lb. Properly equipped, the mid-size truck duo will be rated to tow up to 7,000lbs when it goes on sale later this year. No further information on the optional 2016 2.8L Duramax diesel engine was released at this time. Chevrolet/GMC Press Release Chevrolet Colorado and GMC Canyon Top Segment in Power DETROIT – The 2015 Chevrolet Colorado and GMC Canyon will have the most horsepower in the midsized truck segment when they go on sale this fall. The Colorado and Canyon’s available engines provide customers choices to fit their varied lifestyles. The 2.5L I-4 has been rated at 200 horsepower and 191 lb-ft of torque, while the 3.6L V-6 is rated at 305 horsepower and 269 lb-ft of torque. The Colorado and Canyon will also provide class-leading maximum trailering capabilities, with the capacity to tow up to 7,000 pounds when properly equipped. That’s more than enough to take a truck full of friends, gear in the bed, and a trailer full of toys to your favorite weekend adventure. Each engine features direct injection and variable valve timing to make the most of power and efficiency. Both engines are based on proven engine designs found throughout the General Motors’ family, but are optimized for the demands of truck use with the latest technology for improving performance and efficiency. This includes torque at lower RPMs for better towing power and a more confident feeling while pulling a trailer. Both engines are matched to a six-speed automatic transmission; a six-speed manual is available on select extended cab 2WD models. The six-speed automatic is tuned specifically for the truck engines, offering features like auto grade braking and tow/haul mode. “Every decision we made considered the wants and needs of midsize truck customers. The 2015 Chevrolet Colorado and GMC Canyon are engineered to deliver class leading horsepower,” said Anita Burke, vehicle chief engineer for Midsize Trucks. “Not everyone needs the size or the capability of a full-sized pickup. Now customers have a viable option in a smaller package.” Class-leading horsepower also comes with efficiency, courtesy of dual-overhead camshafts with variable valve timing, direct injection, and jet-spray piston cooling, while aluminum blocks and forged-steel crankshafts ensure a long-life cycle. The Colorado and Canyon will be assembled at GM’s Wentzville, Mo., assembly plant with start of production in fall 2014. Attached Images: Click here to view the article
