They said it can hurt the cats if you read the lit. I have no cats so far on my car. I have one just have to hook it up. but not sure will until spring as dont' see any point hooking it up to the clutch switch if go auto right away.

It should be a cool toy even handy in an auto. Have it in software in my talons. Combined with the anitlag option which it has should really be able to crank in some good boost off the line.

Well one way to find out hook it up already!
I have one but its not hooked up .Not sure want to tie into clutch with it as going auto likely right away and then you wire it think with an on off switch .Have line lock not sure if getting trans brake. My car is street car not track car so cant' see using the trans brake more than couple times when will track the car before it gets retired from the track.

The two step also has antilag capability . You need a bar sensor on there to use it .So possibly two bar sensors to run speed density and the two step reading boost.
Antilag should bulid some good boost combined with the two step. Hope you have a good rearend!

It will work on the maf. I would suggest going to a SD tune.

I have it on my turbo car. Turbo is a gt4276 1.12 ar. Truck manifold turbo setup, with the 2 step @ 4300 and i am pulling 8 degrees of timing with it, i can make about 5 psi out of the hole. The car launches pretty consistent low 1.7's with a good burnout.

I think i can get some 1.6's by turning it up a little, but gota get the car running good first.


Chris

Ps. i have the LPE unit. Works great.

I better be cutting better than a 1.6 60' with my setup. I cut consistent 1.5x's on motor before the turbo setup. FWIW I haven't heard of them causing damage

If i was a stalled auto i would hope to be cutting better 60 ft as well. But being a 6 spd, with a 3.50 gear and a turbo thats a little on the big side for the ar i dont think its to bad. I am also on stock 17 rims, and havn't really taken any weight out of the car, and have crap front suspension on the car.
I have strange stuff to go on the front now.

Also motor cars are easier to get out of the hole then a turbo car. Thats why turbo cars tend to run higher trap speeds then a similiar time motor car.

I'm on all stock suspension myself also, with no weight reduction either, and ran with 16" m/t drag radials. We will see I guess I plan on getting some more welds and doing some rear suspension mods.

what about using N20 and the 2-step?
use the 2-step on the line than when you drop it, have the N20 kick in
i want to cut some 1.6 or 1.5 60 ft but maybe that is wishful thinking
