well i am getting a sct xcal and some 4.10's .... which would you get first .... would my car run ok with 4.10's first for about 3 weeks untill i got the xcal . Also I am ordering my xcal from THR or Brenspeed , which ever people think is better so they can custom load a tune for me. Also i had 1 guy tell me when i get the 4.10's installed to drive it easy for 500 miles and then bring it back to shop to rechange oil out and then i can get on in hard and i had another guy tell me i can get on it hard as soon as i install the gears. Has anyone ever herad of taking it easy for 500 miles after 4.10 install to let gears settle or whatever hes talking about, sounds like it makes since but i dunno. Also is it worth it to get the complete gear kit with all the bearings and what not or just the ring and pinion. Any suggections i would appreciate alot.

 

yea take it easy and break them in nicely. also your speedometer is gonna be way off so the tuner or somekind of speedcal is required

 

youll be okay with the 4.10s 1st, the only reason a tune is needed is to fix the speedo, and yes take it easy on em for 500 mi

 

cool, i never used a tuner before , is it pretty easy to load my tune once i get my xcal in. How do i use the xcal, and whats the differences in the xcal2 and xcal3 , there both the same price.

 

500 mile break in to make sure everything is working right.

 

It will be fine to install the gears first. I just would not drive it much because it is going to run up the miles on your odometer fast until you get it corrected.

 

i would wait and buy them both at the same time. i bought my tuner a while back knowing i would do gears and bigger wheels maybe cutsom dyno tune later on in the cars life.

 

Cool, thanks for the info...
