Think I have said this before but lets try again You have the 140's why not throw them on there and see what you get? Easy enough thing to swap out.

I think you already know this but just for a refresher. I have 110's in my heap at 2800, had 120's in the Valiant at 3470 and the old Duster had 110's at 3050. The Vega has 90's if that matters
