Compression numbers in relation to dyno numbers

Hey guys

Got the car dyno'd today, after a few weeks ago getting it compression tested by go48. It got 175, which is a little low for what I thought it'd be getting. It is stock except for a tanabe exhaust.
The fuse was not pulled, he said he turned off the dsc though.

When I did get back in it after the pulls, traction light and the abs light were on. Had to disconnect battery and the traction light was still there, car wouldn't hold idle either(stalled). Finally all the **** cleared out.

Either way, here are the numbers. Seems pretty low so I wanted to get your guys thoughts. Looking at the sheet, doesn't seem like he went up to 9k. It was a dynojet

are you driving an auto trochoid?

i havent dyno'd my car. but im pretty sure im putting down more than 167whp. we have seen rx8s run 14.4s in the 1/4. you need more hp than 170whp to hit that in a car that weights 3180 with driver.
