if i get a tune this summer and have my rear o2's deleted and egr and then add longtubes later, will i need to have it retuned?

 

I dont think so... just make sure you have everything setup for a catless exhaust and everything in your tune brfore hand. I drove mine like that for a few days before I finally got around to putting on my LT's and some other stuff.

 

You may be a little rich after the swap.

 

**** mine was rich before the swap and is still rich

 

I'd get tuned after the catless exhaust/header install. You may be able to turn all all the codes associated with sensors 2 but you will still be runnning rich after you intall them.

 

well my orginal plan was to get a nelson dynotune early summer then have hi send me a computer when i get my fans and when i intially had it tune turn off the rear sensors. but i guess i will have him send my a tune when i first do my fan swap (so i don't have to drive to SA) then after the LT's i will go to SA and have it dynotuned for all the goodies
