hey im new here and im not the greatest tech guy when it comes to cars, but i do have a question which i cant figure out, maybe you guys can help me. I have a 1998 GP GT with the 3.8L (non supercharged,) with 147*** km's on it. I have a K&N CAI, mangaflow mufflers, and new wheels. By factory it says my car has 195hp, with a stock 0-60mph in 8.1 seconds? My car should have around 210hp im guessing, and i am getting 0-60mph's in 9.9 seconds. I have had the fuel injection system cleaned, i just had a tune up with new plugs, distributor, fuel filter. Is there something else that i am missing? because i should at least be getting 8 seconds flat. Or am i just an idiot when it comes to starting off? With my new tires i am almost getting zero wheel spin when i launch off. Oh and by the way, my new wheels are abit larger and wider. Thankyou in advance.
