[Diy_efi] traction control & nitrous (devlish combo?)

[Toyota Supra]

scott,

when do you plan to install the kit? i have been going back and forth about 
getting this, i am very interested to see how it will improve your 60 foots, 
and if it makes the car consistent.

also, approximately how much was it?

thanks

-j
