Sluggish

Post by Mmes2183 »

Hey guys I have a 21 Silverado 5.3. I installed the 87 octane for now to mess around with it. I also added 15 percent boost with dod off. And the truck feels sluggish like I have to really hit the gas to get it to go. Any recommendations? Thanks

you think it feels worse now than it did pre-tune?
try setting the throttle back to 0?
