Finally ran my Vortech'd '12 in the 1/4 mile, not too happy with the results!

the shift into 5th is hurting you for sure.

your 60's are hurting you for sure. you are .2 off on your 60' which is at least .3 in the 1/4.

you get your 60's to 1.4's and your running 10.8's already.

My vortech auto with the stock converter and 550rwhp went 10.8's.

As we talked about in pm's. Personally, I think some bigger injectors and someone that can tune the maf (Jon Lund), and you will get alot more out of the car.

What is the safe limit for raising the redline with BOSS manifold ?

Here's a snapshot of your fuel curve from the dyno run:
FYI, Ford documentation states TQ will be reduced if Lambse shows lean.
Maff isn't a big deal. It can be easily rescaled.

That data is not from a pegged MAF. IF the MAF is pegging the widebands will still be able to maintain the commanded A/F in most instances. Not the right way to do it, but would still keep the A/F correct.

There has to be something else going on to be causing that, but I would need more data.

How much boost is it running? I just noticed that load is over 2. Something seems off.....

Also just noticed that the MAF is at 11.76 Hz. Tons of room left

Just read the beginning again. It's the injectors causing it to go lean. Has nothing to do with the MAF. But the maf transfer is probably way off right now based on what I can see. Shouldn't be at a load of 2.

That is likely being caused by trying to fix this problem by adjusting the MAF curve. Because the injectors are at their max, this will not work. But raising the MAF will still make calculated load go up and what you are seeing there.

If you are shifting to 5th right before the line trap speed will be off, sometimes way off.

Remember, trap speed is calculated over the last 60' of the run.
Shift anywhere between those beams and it will affect it.

They figured out the issue I believe. It has nothing to do with the shifting it has to do with the traction control/sport mode tuning done in the factory computer, they don't allow adjustments for 1 of the perameters..
