When to tune??

After getting long tubes, ORYP, 02 simms, lid, filter, BGRA, and MAF installed, will i need a tune?? Also, will adding a z06 MAF make much difference on this very slim bolt on system??

Thinking about not getting 90mm intake/TB till i get heads/cam. Do you agree, or should i get the intake/TB installed anyway?

you won't need a tune after the headers, but you could probably benefit from it. install the intake now just for fun

tune can only help, if you've got the cash go for it.

i ran my car without a tune with most of the boltons and it went 11.7s @ 118MPH in the 1/4..

some cars need a tune badly after headers but most dont.. you can always benefit from a tune but its not totally necessary with boltons

It seems that M6 cars fair better w/o a tune than A4 cars.
