4.10's
 
well got the car slightly tuned this weekend. (not a full tune cause i dont have all the parts yet but wanted to fix the speedo).

turns out i have 4.10s.

also found out that there used to be a sway bar, different lid, and it has a fuel cutoff valve on the end of the driverside fuel rail where im guessing it had nitrous from the first owner cause the guy i bought it from didnt know a thing about cars. also i can tell it had completely different exhaust on it so now im scared shit is gonna fall apart. it had a stock tune on it and it runs great still but with the 4.10s and signs of nitrous, im worried the first owner beat the crap out of the car.

anyways im also curious as to what mpgs i should be getting with the car tuned for 4.10s in the city? i got 150 miles in a 1/4 tank of gas doing 70 coming from back home on the highway but since then ive put about 90 miles and burned a little under a half a tank. granted ive gotten on it a little bit when an 05+ gt wanted to race (silly horsey)

If it didn't blow up on spray you think its gonna blow up on the motor? Why would you even be worried about that?

im just worried about if it did any damage thats just waiting to fail. watched the guy as we were logging for part of the "tune" lol and had no KR and fuel trims werent off but then again i have an exhaust leak so its dumping in more fuel.

my main concerns are the rear end, tranny, and getting the rusted manis off lol. im afraid to unbolt everything for the lts cause they are pretty gross.
