Dynos are tuning tools. You could dyno 290hp and be making 60hp more than stock or 60hp less than stock. So run your own before/after dynos to make a comparison if you're interested.

That is the part that your confused about it seems. Dyno's are measuring tools based on the same car with various modifications/tuning improvements. However, my baseline was done on a different dyno so the results are irrelevant.

However, the gains with the intercooler and exhaust are actual, and that is exactly the purpose behind me going to the dyno. Easy as that.

Tunes also increase driveability of a vehicle giving you a longer or larger powerband, so while you may only see a 10whp gain on the dyno, you may see 5 tenths of a second in the quarter mile.

There are three in Ontario.

Cayuga, Ontario has Toronto Motorsports Park
and
Grand Bend, Ontario has Grand Bend Motorplex.

Then go with a catted set of downpipes - or weld in an extra resonator.

downpipes are you next mod for sure, they really help. I'd go w AR.


oh, and i'm pretty surprised at your 110mph trap for 370whp........should be more for sure.

How were the conditions at the track.....was it hot again?
