I am wondering what is the best kit, whether it be TT ST or SC for the easiest install, least amount of ups needed with it, and what will keep some if any of the factory warranty?

I want a kit that will require an initial tune without needing a new ECU, and won't need another tune for awhile. What can I do?

 

Find an Infiniti delaer that will install a Stillen system. Expect to pay somewhere near 7k depending on tax and labor rates.

 

Nothing against SCs just *** motors werent bred for them in particular. I mean they work, but Turbochargers on more ideal for them.
