Anyone doubting the existence of factory freaks can simply take a look at the Nismo section. They're all factory freaks!  |
1. Don't know, it's all hearsay. You tell me how that would happen? My guess is there were other things going on with that motor or the tune that were not explained. Maybe that one revved to 10,000 RPM's.
You're saying these were all unmodifed, bone stock engines with a stock ECU tune? I call BS on that. There is no way a four banger made nearly 40 more horses due to a lucky engine build or ECU transient modifiers such as fuel trims and ignition advance.
2. The Nismos have a different tune, my guess being especially in the VVEL.
Seriously, what would be the logical possible cause of the alleged factory freakishness?
The only major variable is going to be how well the engines break in, which could result in small differences due to compression. For the rest, the ECU is going to keep the tune fairly stable so long as nothing else is changed.
The biggest variable will be the weather.
