Like I said by bluebook values, the cars should be around $8k in middle TN, but there are not many listed on Craigslist in Nashville right now, so most of them are at dealers which would explain the price tag I assume. I did find one GP GXP with 110000 on the odometer listed for $5200 and I thought that was reasonable.

lol ive been exploring the trans settings and its shocking how soft these transmissions are stock from the factory. I made some pretty big modifications to the force motor current tables today (force motor is basically an electronic pressure relief valve for main line pressure) just waiting on these damn tires to get here monday to test these settings out, see if i can squeeze it a little bit more.

nah, when i bought it, it was trashed remember. It's possible that the increase in power is softening it up a bit, but dave said its typical of what he expects of a JTFM by what i described. I'd be curious to see how yours behaves. If i get some free time and open road where i wont get a ticket, ill take some video so you can see how soft it is. The car may pull like a freight train in the high rpm, but you can rev that bitch to the moon just by tapping the pedal to the floor real fast and the car wont respond to it, thats how soft it is. I want this thing to snap your neck when you punch the throttle, its doing just the opposite. You can tell the STR is very low on these converters.
