Since the engine in my F150 (and the one in my Bronco, once I own one) will RARELY see over 2000 rpm, any tune that boosts power only at high rpms is worthless as far as I'm concerned.Here's a beefy 2.7....same engine and tranny that's in the Bronco.
Show me the torque curve from 1000 rpm to 2500 rpm. That's the only range I'm interested in. I want a truck, not a race car. But no doubt about it, the 2.7 is a stout little engine.
