Question: I'm finishing up bolt on mods on my g37s; about when would be appropriate for me to get a tune to prevent power loss? I only have z1 MAF silicone deletes, stillen gen 2 intakes, and a topspeed axle back exhaust...next up is the y-pipe, intake plenum, headers, and (preferably) HFC, but I'll go w/ TP, resonated or not...

Might be the wrong section, I dont know everything about tunes but the best would be after 3 air mods

Once you do the intake plenum and/or headers :twocents:

Although a tune is valuable at any point. The improvement in throttle lag by itself is worth it to some.
