When to tune?
So when is it a good idea to get a tune and which should I do (dyno tune or just get a handheld tuner)? With my mods in my sig is it a good idea to get it tuned b/c I think it might be running rich from the midpipe and all the stuff bringing in more air. Let me know and any help is appreciated!

a sct or diablo would control the running rich and calibrate for the gears, and maybe give you a few horses but if your lookin for more power from a tune then you need to head to a dyno tuner

RE: When to tune?
dont adjust your A/F ratio unless you have a W/B meter . get the dyno tune but you probably dont need it . it will smell alittle rich w/ catless pipe . plus it's supposed to run rich on cold start-up's . I do my own tuning so I know what the fuel table's look like in the tune . it can get as rich as 12.5:1 on cold start-ups . thats also what it's programed to run at WOT (12.58:1).
edit: those are stock value's .

From the factory they are usually around 14:1, or 13.8:1. 12.xx is way rich for a stock car.
You don't need a tune atm, but after the gears you will need some way to correct the speedo. If you buy a handheld now that your local shop can custom tune with you arn't wasting any money with the handheld.

this is how it is :
stock closed loop(part throttle) = a/f 14.64
stock open loop(WOT) = a/f 12.58
if you dont believe me I can show you the table's .

My car was running 13.6ish on the stock tune. My LTs and exhaust were forcing it more to the rich side though.

You can show me anything ya want, but I have seen plenty of them (including on my car) on a wideband (aka being dynoed).
