I have built a 1953 Chevy truck with a complete drive train from a 2000 silverado 5.3 and 4l60e. The Harness was sent to ls performance to be cut down and a tune was done based on the engine specs and cam along with the trans and all the stuff being taken off. The truck is stupid rich at idle, Dies in gear, wont hardly stay running when you let off throttle..
What would anyone need to help with this.
i think it is just a texas speed 226 cam with springs and pushrods, Shorty headers, 4:10 gears. They deleted all the park nuetral stuff, Egr, Ac, all that factory stuff..
Thanks in advance
