In my sig is a list of my mods. If I add a 75mm tb and plenum and cold air intake do I need to get a tune? Would it help to get a mass air sensor while doing all of this? Also if some one could pm me a step by step of this whole flip your quadra shock if your gonne run a 18x10 or 10.5 in the a$$ deatails it would be greatly appreciated.

 

No you dont need a tune, and i have never heard of the shock flipping, i dont think ite even needed, i run that size out back, there is no rubbing!?

 

get some lakewood traction bars from summit for $189 and they eliminate the quadra shocks completely. I no longer have them on my car!

 

I am not getting any rub on the quad shocks with DD bullits and 315s on the back. However, if you do you can install a set of control arms and then eliminate them completely, all they do is reduce wheel hop.

So far as the intake stuff, you should not need a tune, or even a MAF really. It might add a LITTLE, but until you go FI you really don't need any thing bigger than the stock MAF.
