As far as tuning, I am confident in my tuner, Kenny Dangler, from Northern Performance in *******, MI. He is currently running a 181 mph quarter at 7.75 and just did a 205.99 mph half mile in his self tuned 2001 Turbo Camaro at Battle Creek Speedfest. Hats off to him for all of us way up here in Northern Michigan!

My 99 TA M6 with heads and cam that was getting 27,5 mpg with 4.10's had a 224/224 .581/.581 lift cam XER cam. Even with just a good mail tune the car had near stock drive ability. It was excellent in heavy traffic and even good creeping in parking decks.
My 91 RS with a 383 LS1, 229/229 cam and 4.10's can get 24 mpg.
Both cars are six speeds but an automatic would probably react very similar.
With good tuning Cams in the 224/224 to 230/230 range should not be to horrible on mpg maybe cost 2-4 mpg depending on driving style and tune.
