running Map5 as well.....Great tune IMO....i could not want more power, it scares the shit out of me already when going WOT...so i usualy run half the three quarter throttle most of the time..WOT for the special timesl Unless you are trying to run quarter mile blasts this car is fine on Map5.

Quickest way with your setup:
Make sure your car is completely empty. I would idle out, or drive around the area you will purchase the fuel until the car reads 0 miles left. Buy some unleaded Race Gas. (Like MotorSport 109, aka MS109) Run a race gas map, be impressed, and hang on. |

I don't have a gauge but according to the description for map 5 it's should be 13-15 lbs. Also, don't you need more mods to run a race map? All I have in an intake and BOV

you really should have catless downpipes to move up to map 7 or higher, even with meth or race gas. at least i would, the lifespan of your turbo's would be significantly reduced running more boost on the stock downpipes/cats

There's a good amount of selection across this board on the commercial section of this forum. I'm going to be a bit bias so I'll keep my comments to myself But you should find more info in there

Catted or un catted? I use my car everyday for work so I was gonna go with the catted but I also want the most HP gain out of the DPs. Is it ok to you the Uncatted for everyday driving?

Well depends what you mean by is it ok to use it everyday. The only downsides I see to the DPs are an error light that says your cats aren't working (which can be fixed), and the fact that when you have those downpipes on, you wont pass smog. Obviously if you keep your stock DP's then you wont have to worry about that because you can just swap them out, and pass smog.
