Sure beats the $1000 plus you will spend on an aftermarket cam after you buy the incredibly over priced cam, the over priced phaser limiter, a tuner to keep the CEL off... With mods like he has the gains should be even more drastic. This truck barely seems noticably less TQ at low RPM power with a fat jump as the RPM goes up, no tuner or anything. It is still happy even loafing down the road @70mph under 2000rpm.
