Broncfan617 Posted February 8, 2018 Posted February 8, 2018 I am a new member to the site. I am a very loyal Chevy/GMC driver. Many Suburbans, a Tahoe, a Yukon XL, and now a 2015 Sierra 1500 Denali with the 6.2. The new truck pulls better than my 09 Yukon XL did and overall I am very happy with it. I am looking for suggestions for after market mods that will deliver more HP. Up until now I've always driven these vehicles stock but am looking to make some upgrades to this one. Where does one start?
nowicksl Posted February 10, 2018 Posted February 10, 2018 Welcome! Best bang per HP upgrade is a supercharger. Let us know what you do and with pictures of course!Sent from device. Excuse errors.
