2018 GMC Sierra SLT 6.2 - Well that escalated quickly…

Hi everyone,

 

Hopefully I got this in the right thread. About a year ago I had been jonesing for a 6.2. Had a tundra 5.7 and was just really bored with it and it’s limitations. Found a beautiful, lowish mileage 2018 sierra slt 6.2 in summer of 2020 and have been tweaking it ever since. Have since added:

 

Denali grille

2” motofab leveling kit

22” TIS 544bm wheels 

Speed engineering headers and y pipe 

Borla atak catback 

Whipple 2.9 supercharger 

Custom dyno tune by 5 bar Motorsports 

 

Pretty happy with build. Spun rollers to 512whp and 527wtq. Probably would’ve got more without the big wheels and tires but it exceeded expectations and its everything I wanted (for the time being 😊)
