Ok, so follow up question(s).
What would need to be done to see some benefits utilizing the 4.2 ECU?
My truck is under the knife so lots of options are on the table. I have a 4.6 camshaft I could toss in.
What about 4.6 crankshaft and connecting rods?
I've heard of people using the above with both 4.0 pistons and 4.6 pistons. What's the better option?
