and I am freaking excited I love driving it around…I think i put on 700km in 4 days lol..
But I am just wondering if anyone knows a good place to get it dyno'ed in Mississaugarea I don’t want to go tooo far out of the way to get it done.
The car feels like it is lacking some slight HP and I just want to get it checked out to put my mind at ease.

I noticed that but i dont feel like waiting 2+ months to get it done...if there is something wrong with the combustion i would like to get it fixed now rather then later.. but thank you!

A compression test will let you know if there is something wrong with the basic engine, the dyno number could be any number of different issues, not to mention the dyno numbers are usually all over the map.

you can get a compression test done with you and a friend for like $20 or something.

buy a kit at cdn tire. and then follow instructions in a service manual.

You cant get an accurate compression test from a regular compression tester. The one we use measures each face of the rotor as it turns. It is almost impossible to read 3 different reading per revolution of the rotor.

I am aware of the procedure using a standard compression gauge, however you cant get an accurate reading of the differential between the faces of the rotors that way. What we look for is the difference in compression between the faces of the rotors to detect a problem.
