mac lt's and prochamber q's
 

hi, i have a 97 gt auto and i'm gonna install mac lt headers and a shortie prochamber to compliment my amer thund catback

a few q's...

1- which mil eliminators to use? pro3i's ok???

2- should i do this installation myself? i did the catback but this is a whole different animal.......and if not, how much will ur average shoppe charge for lt's and middy installation??????

3- Do i need to get a custom calibrated and flashed computer chip after getting the lts and non catted prochamber?
The only mods i have are the catback and a drop in k and n
is a custom tune needed? i heard gasoline smells and oil smells may occur? would i be running to rich if i don't get my dynotune?

so shall i get a custom tune with the lts??

and if so...which is truly best? fordchip? autologic? diablo? where!!! i'm on long island which shoppe is reccomended for my exhaust work and dynotune??

thanks alot!!!!
