GTM Supercharger Stage 1 w/ F.I. LTH

The reason why we rate it in hp, is that there are too many variables involved in wheel horsepower numbers: temperature, elevation, gas quality, dyno type (and dyno setup), and the car itself.

So far, we have many customers that have installed the system and they are on target for the average horsepower we anticipated. At no point did we ever say that our kit is going to make 460whp.

The mistake he made is that you do claim 468 BHP, not whp. To be fair to him, you do show 452 hp on a stg1 graph @ 8 lbs that seems to indicate whp (never seen BHP displayed on an actual dynograph before). Mostly, just a misunderstanding.
