OK finally got my 4.10's in and running ok a bit whiney but there motives its come to be expected. i have not noticed much of a difference compared to stock and its not calibrated as of yet looking for a shop to install the for racing calibration kit. i wont attempt it myself in fear of fucking it up. is there anything i can do to have it perform better?

youl should feel i nice increase in the upper rpm range. like past 3k. i felt it in mine.
go on the highway in 4th at like 4000 and nail it, youll notice the difference lol

save your money and get a handheld tuner. so much more you can do with them.

for now just use this link http://www.corral.net/tech/gearcalc.html and you can figure out your speeds

in 5th gear.
1500 = 41 mph
2000 = 55 mph
2500 = 71 mph
3000 = 83 mph

well i notice that in lower speeds like below 80km its off by 20km then at hwy speed it incresses to 30+ and the spedo arm sweeps fast clock wise of course im sure its not incresessing speed that fast but not sure why it does that. but it looks cool.

Hurry up and caliberate it, you'll end up putting miles on your car that you haven't drove!

after my 410s i took it to ford to get a recal and they said they couldn't do it. So i just bought an SCT tuner for it.
