I have a 98 gt with full exhaust, Pi head, cam, intake swap. accel coils and taylor wires. Just recently got the diablosport predator and am using the diablo tune function, i havent touched anything else. So i called to see how much a dyno tune would cost and its going to run around 300-400. How much hp/tq do you think i will gain from a custom tune? Is it worth it?

Spend the money on the custom tune. The mail-in tunes are garbage. You'll see more with a dyno tune.

well before a dyno tune, i ran a 14.30 and after i ran a 13.68 so yea its worth it. Before the tune i was making 223.2 RWHP with the "canned" diablosport tune, and after the dyno tune i now make 250.8 RWHP. I have a 2002 Auto GT and my only mods are TB/plenum/cai and X pipe and catback, and i NEEDED the dyno tune. Deff worth the money
