I will be doing a few mods over the winter to my z.

When done I will have.
-224/224 .560 .560 lift 112lsa cam.
-Long tube headers with off road x-pipe with bullet mufflers dumping before axle.
-LS6 intake
-3.73 gears
-Everything else in my sig- lid, ssra little things

What is my best route to go for tuning this beast. I want driveability but would like to be pushing the 400 rwhp nuber which is achievable by a good tune with this cam.

By closest dyno is in chicago which charges 500 bucks and I have to drive there.

I was thinking a high quality mail order tune

any suggestions?

thanks
