for some reason i recall dark horizon had a nice setup that i wanted to imitate on the TR but we spool too fast as is...
one thing i wanted to play with the oem pcm was to make a 2 step using the range switch input to fool the pcm into thinking your in R when your in 1st at the line by breaking the signal "b" circuit iirc...voila cheap 2 step
one of these days i was gonna play with it on my 97 gtp
while your front engine is more powerfull just remember that power is more usefull at the front past the 330
that rear with the smaller turbo is gonna start ripping right away, and id bet its tq curve is far fatter down low where you want it till the front can start pulling its fair share without rippin the tires off....
