Street car mainly. Putting a tko 600 in when I do the turbos, once I get an r block 363 built, or blow it up, I'm going to switch to a c4 and drag it probably.
My sisters husband has a tuner that did his 438, he swears by him. Apparently he can give me a toggle switch setup for 3 tunes, economy, street and race, all for $400-$600. Just hit the switch and change the tune from the sounds of it.
