Default More boost needed - Edelbrock 1567 e-force

I'm looking to install a 3.5" pulley on a 2011 GMC Yukon Denali AWD 6.2 that has the Edelbrock 1567 e-force supercharger on it already.

Does anybody have any belt length/size info? Edelbrock tech support gave me the part # for the pulley, but wouldn't/couldn't give me any info regarding belt length....

I am currently running the Goodyear 4061187 belt with the stock pulley that came with the Edelbrock 1567 supercharger kit.

Also, I'll be in need of a tune....I have access to an EFI Live FlashScan V2 and can buy additional licenses but have never used it before and have no experience with EFI Live tunes. Any suggestions are much appreciated.

Cheers,

you may need a bigger od idler pulley as well. if going to smaller upper pulley. either change will affect belt length.
best way to figure belt length is to install parts and do the ole string method for measurement. and match up string to belt at auto parts store.
