Planning for FreekTune
 

I have a 2012 speed 3 with a few basic bolt ons and am planning for a freektune. A 3 inch jbr intake, egr delete, hpfp internals, atp catless downpipe, forge bpv, JBR 88A motor mount, grimmspeed ebcs and Cobb access port. My future plans are a cat back exhaust, bnr s4, fmic, pcv plate, 3 bar map sensor, injector seals and possibly race headers. I plan on purchasing a dyno tune from freektune. I'm wondering if anyone could share knowledge if these mods should be suitable for a s4. Any other things I should do in preparation for this build?

All of those mods look fine for an s4. I have a freektune and really like it. If you have access to e85 you should use a blend for more power. I am using 4 gallons of e85 per tank

Make sure you have new plugs gapped to .026-.028 and absolutely no boost leaks.
