I'm confused with these results, so does that mean the 180hp is a farce?
2011 Kizzy SE AWD Deep Sea Blue

No. The engine may produce 180, but there is drive train loss, and a gearing issue with the CVT.
Normal drive train loss for fixed gear cars.
FWD: 10-15% loss;
RWD: 10-18% loss;
AWD: 17-25% loss.
Even though he ran the car in FWD mode it probably did not truly function as a FWD car. In addition, you typically want to run a dyno test on a fixed gear ratio of 1:1 . The CVT doesn't really let you play that game so you are inducing error.
((180-127)/180)*100 = 29% loss. which is high, but the CVT makes the test invalid anyway.
The dyno run should only be seen as a baseline test. Modifications will still produce results and they should show up in the dyno test.

for a comparison the sock AWD CVT nissan Juke which is suppose to have 188hp at the crank only produces ~135 at the wheels and it is lighter and turbo charged.
The kizashi is way nicer than the juke and gets better mileage. Don't race a FWD JUKE... It will spank you.
127 isn't great, but it isn't all that bad either. The CVT looks like it keeps torque delivery in a good position throughout the run as well.

^what moto said. The dyno should be used as a before and after comparison only. There are too many variables when it comes to dyno'ing AWD CVT in FWD mode. The purpose of the dyno is to verify dynotronic's claim.
My friend has the ecu right now cus it arrived after i left Canada for vacation. I will be back in a few days to put the ecu back on the car. Prob wont have time to dyno the car until mid to end of oct though.

Like i said before, I didn't have a chance to drive the car yet. ECU arrived at my friend's place AFTER I left Canada. I will be back in a few days and put the ECU back into the car. So long story short, i haven't driven the car yet and the ECU is still waiting to be put back.

Quick update, just put the ECU back in the car the drove to work. First impression, there seems to have power gains throughout the power band. The car also seems to accelerate faster. But all this might be just my mind playing tricks on me since I haven't driven the car for over a month now. Only a second dyno will give the exact picture of how much power was increased.
