Only so much you can do on the street.
It would be interesting to see how a higher stall torque converter and drag radials would work for you.

I wonder why they use two different systems.

Last season they actually had a traffic light..., seriously.
The amber light was prestage...when the red light came on you STOPPED, staged.....then the green light would go on....GO... SIMPLE.
Ill see if there any videos out there from that night...there sometimes are.

109mph top speed, what rpms are you at when you cross the line? 2.2 auto?
how about tires. drag DOTs???
great job, thats fast!
maybe you do need that 3.09 on the auto!

Even though the rev limiter was slightly raised by the chip change it was still not enough to run the car without shifting into 4th.

Tony,
Yup, you are right. The auto trans shouldn’t even be close to 4th at the finish line.
Is the data logger part of the G-tech or is this something else?

i have teh Aux box as well. I have it set to Log afr, rpm, boost, dwell, fuel pressure, I/C discharge...it will log anything you can make a sensore for. Next one im going to try is ignition timing.
Ill run down and pull the files off my laptop.

this is the 12.8 log
vertical green line is the appx start..redline appx finish 12.8sec later.
The thin grey/black lines mark the area where the data tags along the bottom were taken.
the orange line is fuel presure. The numbers are correct not the unit of measure(volts).
The RPM is appx 200-300 rpm high from what i can gather, not sure why. Ive tried numerous settings on the set up.

Looks like in second gear the injector are maxed out but the A/F radio is still good. You must be running right at the limit of what the injectors can produce. I was told that if the duty cycle goes over 80% its time for bigger injectors. Are you upgrading when the smaller pulley comes?
This is a neat tool, it really does show everything that you need.

If not, that does help a little bit with RPM drop.

Very common term in these parts.
