My 98 gt only has a h-pipe, no cats, flowmasters, upper intake elbow(upper plenum), and gears. If I were to goto a shop would they be able to tune the car?

 

Do youneed a tuner for 98's? I'm not sure.

I might wait for a few more mods (especially intake side) till i tune it.... but you would get a little jump in power. I just can't see paying for the tune when you will probaby have to get it redone again unless the shop will cut you a deal on the return.

 

Yes,[/align][/align]A custom tune will always be of benefit, unless you're planning on spending the rest of your life buying regular gas...[/align]
