" I had my Evolve Xpipe and Stage II tune car over on the EC dyno and it put down 345whp on their DD dyno with winter tires, winter tires have a very material impact on dyno results. Have a look at the attached link for a comparison of winter vs. summer tires on same day/car dyno on a Dyno Danamics. Winter tire dyno lost over 21hp vs. the summer tire.
I want to head to Champion Motors Dynojet and strap it down for a few pulls when I put my summers on as I want to see some Dynojet numbers for comparison.
After that, I am going to head back over to EC and conduct a comparo, redyno with Evolve Stage II and summer tires, then load up the EC aggressive tune and redyno. Should be interesting. Vlad and Slav at EC Canada really seem like good people, they were extremely nice to me and are very knowledgable. "
