My car was tuned at Balanced Performance, in georgia, by Ed on a dyno. The result was a weak 175 whp. We were looking for something more like 230. The cams in the car are crower stage 2 with the bigger lobes. (They might be called stage 2.5 because of the bigger lobes idk). It was being tuned on a p72 hondata s300 ecu.

We think the problem is that the VTEC on the exhaust cam is not engaging. The VTEC on the Intake cam is engaging though. We know that some sort of VTEC is engaging because it does give about a 10 hp boost and gets louder when vtec should hit.

When the ENGINE was out of the car and on a stand, we were timing the cams with a tool from honda that simulates oil pressure by using air pressure. The engine was not on a dyno out of the car. Only the vtec on the intake came was engaging when the engine out of the car. The mechanic said that it was most likely due to a leak and would be fine once the engine is in the car and everything is hooked up.

The dyno chart in my sig is not the actual dyno. It is just some picture of a dyno. The horsepower does start dropping off around 6.5-6.8k. With the crower cams, horsepower should be able keep increasing over 7.5K at least.

left me know if you need any other information.
