On a similar note, what can be done to a Laguna Seca to increase performance other than going F/I (which some would consider blasphemy)? They already have amazing handling from what I've heard, and they're no slouch in a straight line either. Someone humor me here, I'm just curious.

 

Could you get an aftermarket meth tune, and then use your trackkey tune as the DD-lower timing tune?

 

This ^^^^

I've had GT's for too long....I guess I really like the custom feel I get when I mod my car.....Really makes it feel like my car.
I don't want to screw up the things that make the Laguna great (my opinion), but I would like to know what little tweaks I can do to wring even more performance out of her.

 

That is a really good question. I wonder how that would work? How would you upload tunes for the track-key to recognize, if that's what happens after a custom tune on a Leguna Seca?
