 Chassis Dynos are pretty inaccurate and may misrepresent real horsepower and torque gains, which is why Halltech let's unbiased professionals, like Katech Engine Development do the dyno testing on their Superflow Engine dynos. The same dyno used by GM and GM Racing to components, where a clean room, constant fuel pressure, water temps, oil temps, barometric pressure, and clean dry air is used for every pull. This is the only type of validation Halltech needs to prove our claimed power gains.
Chassis dynos are good tools for tuning, but end up promoting a specific product where the company doing the dyno is validating their own product. Not very objective. The numbers become someone's bragging rights or marketing hype to promote a specific product. If you believe the chat on the forums, there is the horrible "Vette Tax" associated with the Corvette, which, it turns out, that if you end up having to replace your intake due to poor design, you must question who is really paying the"Vette Tax"? Click on the Katech icon above for the real dyno numbers, done by the company that dynos all of GMs GEN IV engines and tests and build GM Racing engines for the famous C6.R race cars. This engine dyno was done in A-B-A scientific method, with no changes in tuning or anything else. Just swapping the stock GM LS7 intake with the Halltech Killer Bee™ AAIS. +12 HP and +11 ft. lbs torque was the result, which is why Katech Engine Development endorses and sells the Halltech Killer Bee™ AAIS on all their Street Attack and Track Attack Packages.

The Real Dyno Results Halltech Killer Bee AAIS vs. K&N.
Still running the Halltech F1 Filter? Don't. Here are the results of the F1 vs. our new Killer Bee™, done 10 minutes apart:
New dyno#s with Killer Bee™ AAIS & Tune.I'm impressed! 570rwh/513rwt..
We re-dynoed my red(track car)Z this morning. This car is one of the good running ones to start with, always been stronger than my blk Z. Now I have to work on the blk one some more . The only change from my last dyno was the addition of the "Killer Bee™" intake/maf and a small retune. The air intake temp was 102 and in the dyno room it was 90. I also dynoed it with my HREs vs my stock wheels from last time. We did a direct before and after. Both cars have the same combination, cam, headers, port matched intake and tune. The red Z has no cats and the Killer Bee™ AAIS and vette-air. Tuning done by Carlos:
Here are the results of Jim's Killer Bee™ Attack Stage 1, with Kooks Headers onboard. The important thing here is the air-fuel ratio changes Jim did while the car was on the dyno 1000 miles away through our exclusive
emailTUNE® . Jim was asked to progressively lean this tune out until the air fuel ratio was around 13.2:1. The incredible power result can be seen here. So much for having the tuner at the dyno for perfect results. Click on dyno for larger picture:
How about a dyno from our competition. You cannot get more independent than to dyno your Killer Bee™ Attack package at a shop that does not sell our products, right? In fact, the Vette Doctors, are one the the premier engine builders and tuners in the country, but the have never purchased anything from Halltech and install intakes by our competition. They dynoed our customer's car with just our Killer Bee™ AAIS and our
emailTUNE®.. That's it. The dyno numbers are just short of astounding. Honestly, these numbers are higher than one could normally expect with our Stage 1.
Take it to the max. Dynos near 600 RWHP are coming in weekly now, with the Killer Bee AAIS swarming the air into the LS7 monster motor:
