87 vs. 93 and another question..
I've searched, but didn't find anything conclusive.
Are there any advantages to running 93 octane in a 5.3? Stock heads/ 216/220/TB Converter
I ask because even though I do not have headers yet, my truck still seems to have nothing on the bottom end, and not as peppy overall as it should be. Wondering if the switch to 93 would wake it up.
I don't mind paying the little extra for premium if they HP gains warrants it, but I'd rather not just **** my money away.
Wheatley supplies my tunes, and he asked me if I wanted 93, and I declined, but I'll be needing a retune soon and wanted to see what was the general consensus here.
And I've never had a stalled vehicle, so I am unsure of how it's supposed to be...but until ~55mph, my converter constantly locks and unlocks when just cruising. Is this normal? It's just rather aggravating.
Thanks guys.
