Shell 91-octane, BTW.
Supposedly the HKS brand (not OEM) 370Z plugs run at a hotter temperature and will actually allow for increased HP/TQ gains.
No, nothing with the the TMS system or shift RPM's or anything like that, because of the possibility of voiding warranty on the transmission, among other things..
The tune is mainly air, fuel, timing, and boost.
Pulls were done in 4th gear.
Also, the HKS M-Series performance spark plugs come in 2 heat levels....8 and 9. I'm talking to Miguel to figure out which one it is that he suggests.
As an FYI, they are ~$25 PER spark plug.
