Hello all,
My name is Tanner Larson I am from Seattle, WA but I currently reside in Vancouver WA. I have an orange xD with the DAMD body kit. I recently last summer put in a 550 watt amp and two 10" JL audio subs in my car, they sound amazing and its an ear tickling experience

considering I also have a bass knob so i can control the punch level.
Just wondering for you experts or well seasoned xD folks! =D what are some cheap and easy mods to get a little more punch when i push down my pedal and drop into second or third. I also notice I have very little if any acceleration in 4th or 5th my car seems to top out in third then its a slow climb. What can I do to give my baby a little extra "PAH" you might say?
Any and all suggestions are welcome! THANKS!
