I've owned my 2002 TL-S with Nav for about 6 months. The car is a real hoot to drive, even though my previous car was a 91 Twin Turbo 300ZX (300HP). The TL feels almost as fast, but the Z was getting some age and probably needed some work to get the engine at optimum performance.<br><br>Can anyone suggest some performance mods that are reasonably affordable and don't cause extensive rework to the car? Are there any chips for the car to inprove HP or firm up the shifts when in SportShift mode? How about intake enhancements? Any ideas on potential HP gain with any suggested mods?<br><br>Thanks!

wabbit, You basically have the standard performance upgrades with the TL. Intake, Exhaust, Headers. You can also go with underdrive pulleys, or even an APEXi V-AFC. If you want to get crazy you can install some NSX cams. Check out www.acura-tl.com or www.acuraworld.com for more ideas. The only inexpensive mod is Intake (AEM or INJEN) $220. Exhaust = $500-$700, Headers $1100+. baggs
