03 Silverado daily driver 87 octane settings?

Post by alphamalert »

I'm trying some different tunes on my 03 5.3 and was wondering how to set up shift pressure for softer shifts without compromising longevity of the transmission. Anyone with some other settings for this type of set up , i would love to hear from you

Thanks
