Im having my truck tuned next weekend and wondering what other tweaks I can/should do before hand. I'm gonna have it tuned on e85 so I'm wondering if a better plug runs better with e85 or not. Everyone with ls1's use ngk tr-55's but does e85 like a hotter or colder plug or doesn't matter? My truck is a 2011 silvo with a 5.3 with CAI, modded air box and catback with a xr-1 muffler.

Gap it so the ground strap is square with the electrode.
(Might be a little tighter than you're used to, but the plugs work best when the gap is square.)

Be interested in how well the stock fuel pump holds up to long term E85- Is your truck a flex-fueler already?. People go ahead and give me crap, Run Champion copper plugs gap at .45+ Hope your tuner is good.

The type of plug is less important than the proper heat range.
Even though alcohol burns cooler, leading one to believe it needs a hotter plug, it burns cleaner, leading to less fouling/carbon buildup problems.
Since you are normally aspirated, your current plug will likely be OK.
