recently put a whipple 2.3 on a stock 2005 GMC Yukon Denali. I realized this is rare as not too many people, at least from what I’ve seen, seriously mod these trucks. Stock pulley was 3.75 but I recently installed a 3.25. This is the smallest pulley that I’m going with, so I’m set there. Wanted to go right into a pulley swap immediately since I knew I would eventually do it, rather sooner than later. Only other mods to the truck are Airaid open filter element, Airaid tb spacer and corvette servo. No engine upgrades or exhaust. Wanted to see what you guys foresee me needing to upgrade. Doing a stock ac delco fuel pump with a boost a pump, aem wideband and I’ve pinned the crank. I have a 2 bar map sensor on standby just in case I end up maxing out my maf.

 

I'd want the 2 bar MAP regardless just so you can properly tune the VE table and watch the kpa readings above 105kpa.

I'm surprised that these supercharger kits don't come with 2 bar maps from the get go.

 

Is this an older side mount or newer intercooled top mount?

 

they’re designed specifically for a bone stock vehicle other than the injectors, tune, fuel pump and air filter that the kit comes with. I guess mine isn’t stock anymore since I did a pulley swap.
