I Did What You Almost Did With My 03 Lightning, Got Pissed Over A Problem, Stripped It, Sold IT With Nothing More Than Longtubes, Valve Body, And Custom Tune. Ran Like A Beast. Whooped Pullied Lightnings In That Stockish Trim....Long Story Short, My Tuner Kept Scaling The Maf Wrong So Drivability Was Trash, Truck Died At Stops, And Being The First Daily Driven GT500 Blower Swapped Truck,That Before I Had The Custom Tune On Ran Like A Monster, I Got Pissed And Have It Away. DON'T MAKE THE MISTAKE I DID. I Miss My Lightning, And I Still Talk To The Guy That Bought It, He Still Loves It, And WILL NOT sell It Back To Me.
Hang In There Man, You Will Get It Right.
