A 2004 GMC Denali XL with a 6.0 engine is rated at 20 fewer horsepower than a 2004 Escalade ESV with a 6.0 engine. Where is the missing horsepower? Can it be easily reclaimed?

A 2004 GMC Denali XL AWD with a 6.0 engine is rated at 20 fewer horsepower than the near identical 2004 Escalade ESV AWD with a 6.0 engine. Where is the missing horsepower? Aftermarket chips & tuners claim the same performance gain on both vehicles which would still leave the Denali 20hp short.. Can the "missing" horsepower be easily reclaimed?

It may be in some of the other equipment. Besides, 20 hp won't really affect the truck. Cadillac will also be a bit more powerful than a GMC right off the bat (you're paying for it...)

They probably did a revision to the exhaust, computer, intake manifold or a variety of other things on the caddy to give it a bit of a boost over the cheaper version. This give the caddy a distincion. A performance intake kit or exhaust kit should give you the horsepower jump you want. You could buy an aftermarket chip for it but you may suffer long term reliability issues as the chip kit pushes more fuel into your engine which it may not be able to take for long. I work in the oil field where guys are always chipping there trucks and in more then one case I know of, the engine or transmission has not lasted that long.

Since most vehicles are controlled by computers these days the horsepower in your Denali probably is too. There are plenty of replacement chips available on the after market that will boost horsepower.

Its probably not missing. GM loves to put the exact same engine in multiple vehicles and then rate the fancier more expensive ones slightly higher.
If it is then I'm sure its just reprogramming the ECU which is probably pretty easy to do. Everybody sells them for vehicles that common.

Is this flywheel HP or rear wheel HP? The only difference in the 2 vehicles that I am aware of is the Denali is all wheel drive full time. There may be a variation in exhaust and gearing as well.

In the late 60's early 70's cars had rated horsepowers that where far less than what they really put out, for insurance reasons. The only way do be sure as to what yours actually puts out is to have it dyno tested

the difference in the horse power will probably be in the all wheel drive part of it ,it does take more horse power to run this,as opposed to a part time 4 wheel drive vehicle,you might re-claim some of it with a chip for the computer,but id say that's the missing horse power right there,good luck,hope this helps.

It may not be missing. When car makers rate their vehicles it is rated on which vehicle it is in, what equipment it has, the weight of the vehicle, so it may not be missing
