Default tuning right

my mods are in my sig, i was just wondering if my car is tuned right... it smells like pure gasoline out the tail pipes, the car makes good power but i feel that it should feel faster than it does. it makes power on paper but that doesn't mean crap to me. i want to feel it. i do have a crappy clutch, it does grab but just doesnt feel like a 463 rwhp car. if someone dynos my car can they tell if the tune is good?

dyno it with a wideband on it and you'll know if the fuel tables are right

No, it's not.
It shouldn't smell like raw gas. Must be too much fuel, maybe it was tuned in another city or something has changed and now the fueling is off.

Only way to know is with a wideband. You may want to buy one with a gauge for a permanent install.

Most likely its just too rich but if you tool the CATS off it will smell a lot worse than normal.

it was tuned in N.C. and i am in GA. i dont have cats but when i shut the cutout and the exhaust comes out the stock WS6 exhaust, you can't stand behind the car, and also the car puts down good bit of horsepower but i thought it would feel faster... is this just a bad tune? should i get a driven tune???

Do you know if it was tuned with a wideband from idle on up? Or did they just toss it on a dyno with a sniffer in the tailpipe and tune it at WOT? Makes a big difference in the idle and midrange if it is done properly... Also, do you have any exhaust leaks now that you didn't have when it was tuned? That could cause the O2's to see air and make the PCM think the car is lean and add uneeded fuel (which is also carried over to WOT)... Have you taken it to another dyno to verify the numbers?

^ I agree, it's hard to find someone that will spend the time to tune right.

Then spend a little more for a tuning suite and do it yourself.
I grew tired of paying big bucks to get a semi-tuned engine with a lot of gremlins. Then I decided to do it myself.
Now, tons of reading and a few books after, I have my car running great and I learn new things every day.

If at first you don't succeed, you can try again, and again until it works the way you want it.
