1/8... 9.09
MPH...82.61
1000...11.58

1/4... 13.718
MPH... 106.18

My MPH I know should be closer to 110.

I am hoping to have another tuner look at this soon.

Werts ZFR I tuned traps 121-122 all day on 93 octane. 106 trap is easily done on 91 and stock turbo at 22psi. This Mustang dyno you used seems like it reads close to the same as a dynojet based on your trap speed.

i can hit high 13's at 104mph with gms1 tune on a 2.3 60ft. you should definately be faster unless you are spinning all the way down the track or on a mountain.

An HPT logged 60-100 run may be a better measure versus a quarter mile. A lot of driver skill goes into the result of the latter...

The trap is a dead give away something is not right, though.

I was spinning off the line pretty bad. Keep in mind my car weights 350lbs more than a Cobalt

I am a pretty well versed driver, but I understand what you are saying. I am going to see if I can get the tune from my tuner and post it on here.

I'd have to go check out my slips, but I'm pretty sure I trapped higher than 106 on the KO4+ at over 5300' altitude

Trap speed gives a pretty good idea the power level. Time is greatly effected by the 60' but not so much the trap speed.

Are you saying there's hope for me if I go to the Airstrip Attack next year and run the 1/2 mile with Luci??

They only measure trap speed...

Except your altitude is going to kill your traps in the half by a lot vs sea level 6000ft is high up lol. Good for comparing to other cars running at the event with you though.

My last 2 runs at the strip with the + were 13.56@110 and 13.30@107, but we still have 2ndgear limited a bunch. That was with a 2.32 60ft on street tires. Remember that as your time comes down your mph can drop a little cause you aren't wasting it by spinning. If I ran the times the zfr car ran with that turbo I would park it. Something's wrong.

Sorry, but as it's already been said, your tuner does not know how to tune this car.. my stock turbo trapped 113mph at 2500', roughly 4000 DA and my Zfr traps 124, same track. As stated before, these are considerably different than your average whatever car.. Bosch needs a different understanding so to speak.
Unless... there's something seriously wrong with your car.

I hate to beat a dead horse but that's definitely a low trap. I trapped almost 107 mph on GMS1, intake and exhaust without even a custom tune and obviously stock turbo.

I should have the dyno graph with lambda, AFR, and boost soon to help shed some light

Still having trouble getting the data from my tuner.

Just a thought, I am running the FORGE BPV on this turbo, could that affect the numbers?

I am also running the forge and they are good bpv's. Correction. On my traps, after looking they were 112 spinning, and the 13:30 was 110. I should be in the high 12's by the end of the year. Hope you got your car right.

Here is what is done to the car.

ZZP ZFR6758
ZZP 200 Cell Catted Downpipe
Hahn IC pipes
CS FMIC
KY Stage 3 Clutch

It was an extremely hot day. 96 degrees outside! This was on a mustang dyno, tuned with HP Tuners.

318 Whp
333 Wtq

The other numbers on this graph are from the previous tune they did with the stock turbo.

Any thoughts?

previous run was a 267 whp/ 292trq? and now you see a 318whp with a ZFR and tune? Do you have any info on the previous run? temperature?

If the conditions were similar then I think 318whp for a ZFR is incredibly low.
