Default retune when you move a car to a different state?

would a car that was bought & moved from east to west, across half the USA need a different tune for the changes in sea level,weather differences,DA or ???????

it was built & tuned by a reputable shop & ran in the east @ atco which is 90' above sea level & it ran 10.80 @ 127 with a 1.50 60' in 58* temps....

car is now in the midwest @ 662' above sea level......it ran 11.52 @ 120 with a 1.50 60' in 80* temps.......

so do you think it needs to be retuned for the new area its in because of the difference in sea level or what?

thanx abunch!

I think the only thing that can be said here is: It can't hurt.

If it was tuned via a MAF calibration, then no, it isn't necessary. A speed density tune would be more apt to require adjustment.

If tuned correctly, nothing needs to be done, if it was not tuned correctly, then you may need to adjust it.

nothing has been touched.....

just wondering why the MPH is way off, from the east coast to the midwest.....127mph to now 120mph...so i should expect that much of a power loss????

the car dynoed 475rwhp out east.....it feels like it would be lucky to dyno 400 hear in the midwest.

Well there could be a big difference in DA. There is 22* difference in temp and a higher elevation also how did the humidity compare. East coast tracks like Atco know to be faster than other because of low elevations.

Nah we just know what the hell were doing lol

I would think elevation would have a good deal to do with it though.
