Your trap speed is very low even with that 60'. Are you really mashing the pedal? How many miles are on your F? Was this run at altitude? Depending on your altitude and track conditions, you're trapping about 10mph below what you should be trapping, this is substantial and might indicate a problem.

Yeah good catch. Perhaps your KCLV was crap? I run some octane booster for a few days to make sure there’s no chance of knock before I head to the track. Just enough to push our 92 to about a 94.
Ill have to look again but I believe i was trapping around 110-112

I usually put in 91 octane from Shell (partly due to the fact that it's the only gas in Canada that doesn't contain ethanol) and have done this since I bought the car. I bought the car at 60K kms and it's now at 112k kms. This week I decided to switch to Petro Canada 94 Octane. It could be my imagination, but it feels better. Is TECHSTREAM the only way to check KCLV?

I actually thought the same thing, especially after the first run I thought maybe I hadn't mashed the pedal far enough down. So after the first run I made sure I moved my seat up, and I definitely had the pedal to the floor. And no, pretty much sea level.

In my sig you will see my mods . Exhaust, joez intake elbow,afe dry/ ran on nitto nt05r drag radial 275/40/17 just tried them out as I sold my Hoosier setup as I thought I'd be done going to the dragway but apparently not and bought my brother in-laws setup when he sold his F.

Yeah I think there is more in the drag radial to get out of as in terms of hook up when you have more power like headers, when you add extra 40whp the stock tires will break loose quicker with headers or full bolt ons with the rr-racing tune and intake. I've had similar results before hooking up on my pss as well as the hankooks rs3. I wanted to play with air pressure at the track as my tires were inflated to max spec for driving there. But I noticed air wasnt available so i couldnt do any tire testing and trying to drop my 60ft times by softening them up and hopefully launching better out the hole. Also because its pretty much end of the season here for drag racing there was no track prep and my times in the left lane were much worse due to coolant spill from another car and all they did was mop it up lol. My 60ft were 2.3 in that lane as i would experience wheel spin.

Did small burnout at the beginning but found that the nitto needed a 2nd gear burnout to hook. Got from 2.2 to 1.9 heating the tires more .

I had my ISF dyno'd at the Sikky Block Party today on their Dynapack. I don't have any baseline to compare it to so the numbers don't really mean much. I'll take it though. I last dyno'd my ISF on Sikky's dyno back in 2012(?) with JoeZ intake pipe, Sikky headers, and Borla exhaust. It put down 405 whp. 5+ years later with the addition of RRracing intake box and tune, it put down 430+whp. Once again it isn't an apples to apples comparison so it doesn't mean much. The block party was a blast though.
