Hello, I have a C7 z51.
With exhaust downpipe and X pipe. both without catalyst.
KN replacement filter
And a Tune.
The truth is that the car works very well.
I have done several tests against a friend's C7. and even mine is a little faster.
Today I went to the dyno and I had a bad surprise.
I expected 15 or 20 HP more than stock. Stock is 466hp "supposedly according to the manufacturer" . Well, I was thinking about 490 hp or so.
The result was 442hp engine. and 317 to the rear wheels. with a torque of 585Nm
Why so little power? It is normal ?
The dyno is from the Maha brand. They are very prestigious.
