You might want to do a search on Hennessy. Guy is a real winner. Wheres the dyno, for 7k I sure would like to see one.

 

A good custom tune to remove most of the torque control management would wake the Hemi up considerably. You could have that done for less than a thousand - and I don't mean a handheld unit. I mean a real custom tune and dyno. You'd be surprised what these engines can do unfettered from all tight computer parameters.

You'd have one serious sleeper.

 

Those mods aren't worth the money you would pay if they were bought seperately, which would be way less than half the price of this kit. This HPE450 package is a joke. Its sad that some people have probably bought it

 

Pricey yes, but it's in line for the price you pay for a complete designed kit from a reputable tuner. Also consider it's the only way you stand a chance to recoup a small percentage of your money with mods if you ever sell your truck. Conversely, slapping on one-off mods yourself will for the most part, de-value your truck. You can pay now, or pay later.

Been there, done that with over 70K worth of modifications to two late model Corvettes. I've learned this the hard way, and not just once.

Having said that, the soon to be released Magnuson blower would likely not be much more, and yield a much greater bang for the buck.

 

How about just based on horsepower-per-dollar? If you wanted to spend relatively the same cost after labor, why not go for something like this?
