questions about tunes

[clayton87]

I have been running power hungry's canned tow tune for about 3 months now, I love the way it felt, I think the novelty has worn off a bit , now I'm considering getting a custom tune, probably an 87 performance tune, however I'm also considering maybe an 87 towing tune, My only mods are a cat back and a AF1 intake. What I'm wondering is the real big difference between the two tunes. - fuel mileage (city/highway) shift patterns (earlier/later), throttle response between the two and etc. any input is appreciated. Also I do not tow or haul anything, the reason i used the canned tow tune was cause i liked the pickup affect of it, Thank you
