TSM makes 357RWHP NA on a Stock Longblock VQ37

The after HP # doesn't really concern me. I can make a dyno read pretty much whatever I want to read within reason. The only way to accurately measure HP gains is to do a before dyno with the same car and preferably on the same day (or as close as possible) as the after dyno. Comparing someone else's before dyno to your after dyno is pretty much useless.

What concerns me is that we are being shown a before dyno of 272 (correct me if I am wrong) and an after dyno of 361 (again, correct me if I am wrong) which means we are looking at a supposed gain of 89 RWHP. I'm sorry, but I don't buy it. These are either dyno sheets of 2 different cars and/or they were taken at 2 different periods of time. Show me the before dyno of the same car and the after dyno of the same car taken on the same day (or close to it) with all the other factors being the same, and then let's talk turkey.

Again, if I am wrong, please let me know, because I can't see the actual dyno sheets posted due to the firewall in place at work. I am just going on #'s that are being mentioned in the thread.
