  1. I will check my glove box tomorrow. I have the same truck.
  2. I went with the 2020 2WD GMC Sierra SLE with the 2.7L in mid February. I was able to out the door for $34,700. It has the preferred package, convenience package, towing package, and 20 inch wheels with all seasons(275/60R20). To compare it to the Silverado would be an LT with the all-star package and towing package. I liked the styling of the Sierra over the Silverado. I love the engine. I have 8,600 miles on it. Before the leveling kit and bigger tires, I average 24 mpg on the highway and 19 mpg in the city. After the modifications, 22 mpg highway and 18 mpg city. I have done a lot of tinkering. I added: aFe momentum gt intake aFe downpipe aFe scorcher tuner Borla S-type exhaust 2 inch leveling kit Added bigger tires Wrangler Trailrunner AT (275/65R20)
  3. I have the Borla S-type exhaust with stainless tips. I wish there was a way to get a 2.7L badge like they have with the 5.3 and 6.2. I added the black GMC Decals front and back which probably added 5-6 horsepower.
  4. I ordered scorcher, downpipe, and momentum intake 1st week of April. They arrived 2nd week of June. Got my truck back last week from VR.
  5. I added the downpipe from aFe for more air too. I first used the scorcher from aFe to tune and it worked okay. I then reached out to Vengeance Racing in Atlanta. It took about 5 weeks for them to work through everything. I agreed to be the Guinea pig for their work. I paid $2,600 in total for the tuning, Dyno, and transmission calibration work. I am now running about 29psi over the stock 22psi. The worst part of it all was having to drive my wife's Subaru outback for 5 weeks.
  6. It was running a 6.6 sec 0-60 stock. 6.5 secs on 93 octane. I ran it on 93 octane. The leveling kit I have isn't terribly high, 2 inches. The tires went from 275/60R20 to 275/65R20 I added roughly 75 hp 95 lb/ft on the Dyno. The tune and changing the shift points plus improving throttle response with a pedal commander really helped off the line.
  7. Just ran it today and got 5.6 on 0-60. So about as fast now as a stock 6.2l. It's different strokes for different folks. Would love your thoughts after you test drive it. Cheers
  8. I have a 2020 GMC Sierra SLE 2WD crew cab with the 2.7L. It has the preferred and convenience packages. I was out the door at $34,700. I added the aFe momentum gt intake, Borla s type performance exhaust, I am getting it tuned by a local GM aftermarket performance shop in GA and it first dynoed with scorcher and bolt ons at 310hp/340lb/ft to the wheels with 87 octane So to the crank, I have about 350 hp and 390lb/ft. 0-60 almost 6 secs. I get 24.4mpg on the highway and 19mpg in the city. I have a 2 inch leveling kit and have 275/65R20 wrangler Trailrunner AT (34 inch tires). It is my daily driver, and I never tow. It is faster than a 5.3l and about as fast as a 6.2 when both are stock 0-60mph time wise. Torque peaks at 1500 rpm. It was built by GM to give turbo diesel like performance to a gas motor. It's not for everyone. But to belittle it's performance is ignorant, but Skippy that sounds like your M.O. But it does sound like civic
