Nismo Uprev Tuned by SpecialtyZ

According to Sebs, the Nismos run leaner to begin with, and with the bolt-ons you can see in the baseline run that the car was runnin way toooo lean. I went in to the shop originally to get the car checked out because the car seems to labor more than usual driving in 5th and 6th after installing those parts.

I would definitely get the tune done if you have made those basic breather mods, or just have the ratios checked to be safe.

Your torque curve looks healthier then mine was. Im sure you feel the pull threw the gears. Props to SpecialtyZ
