First Katech Stage 1 C7
Just wrapped this up yesterday. This is the first Katech Stage 1 C7.
A complete package list is available on our website here:

How does it feel? I can't really tell right now because it blows the tires off at 3500rpm and half throttle. I guess that's a good thing.
On to Stage 2...

Halltech Flat torque curve vs. stock
4,000 to 5,000 rpm torque curve, except for a spike in the stock curve, is around 20lb-ft more than stock.
Look at what happens to the stock torque at 5,000 rpm, after peak. The drop off to 390lb-ft vs. 416lb-ft. This kind of torque is usable and you will feel the difference.
We saw the same spike at 4,500 rpm on our dyno sheet. If it was not for that bump in the road, over 20lb-ft torque would be the case with the Halltech C7 Stinger over stock.

Its well known that stock C7 exhibit an 11-12% drivetrain loss of power when comparing WheelHP to Crank HP , this has been demonstrated time and again by stock dyno runs.
You posted two dyno sheets; one shows 409whp which I assume is stock form?...another shows 424whp which I assume is the dyno run with the intake and tune?...14hp gain over stock ...Your website claims this package makes 510hp. Can you please explain how 424whp translates into 510hp or am I missing something here?
