I've got a few more mods than that, but no cold air intake, and I switched from another programmer. The canned tunes work really well. The tunes are designed to work with common bolt ons. I know a dyno tuner personnally, he suggested a dyno tune would only yield minimum gains for me. Another guy I know with a 99 gt has all the bolt ons including long tube headers, off road x-pipe, 75mm throttle body, plenum, etc. He's been running the included 93 octane tune for several years, no issues and 12.8 in the quarter.

You should be fine just installing one of the canned tunes from the predator.
