ok i have some ??? anyone with 3.4 auto fireibrd went from a 3.23 to a 3.73?? i wondering what kinda gains you get in the 1/4 and how much top speed you lose?? ok who makes chips for 3.4's and what do they do exactly remove speed limiter???

 

and also i changed my spark plugs bout 2 weeks ago and i have a lean problem how do i fix this??does anyone have stalls on there v6's??

 

one of my good friends had 3.73s with a stall on his 3.4, he liked it a LOT. I rode in it, and I recomend it.

as for the chip, superchips has a programmer for it, Im not sure if it removes the speed limiter. As for the lean condition, its not because of your new plugs, something else must be going on.

 

no my old plugs looked to be lean not my new ones!.. and bout that stall and 3.73's what stall is it and how high is it.. and how much you thnik ge gained in the 1/4 if you had to guess! and how much is that chip?

 

his was a 3200 stall gains, about 4 tenths in the quarter gears are arnother tenth or two.

 

yea how much did the stall cost him yea i run liek a 16.8 now so i can get like down to the low low 16's

 

stall is about 700 bucks, plus install...
