| :I also switched to the colder IK22 Iridiums Might want to go back to Nissan's coldest TT plug. People have had really spotty luck with the Iridiums. :8 gal. 92 octane + about 8.6 gal. 100 octane to be safe Probably not necessary with 13psi but good to be safe. However a full talk of gas is quite heavy. Try to get it down to under a half if you can next time. :don't bone stock TT's run low to high 13's???? Bone stock on street tires have run mid-high 13s but usually low 14s. 18" wheels with very little sidewall don't help either and your 60' times show it. A 2.0 is a great time for street tires if you can get down to that. To get an idea, if you have a 2.0 on the 14.1 run, it'd likely be in the 13.7-13.8 range. As much as people like to say it, dragging is not easy and it takes time. However, the most notable thing on your slip is your MPH which seems pretty low. Check those plugs (at least the gappings if you don't replace them, but I would), run an ECU diagnostic and go over everything that you can. If the MPH was there I'd say you just need to work on your launch/60' (which you still need to do) but it seems like something else is going on. Good luck.
