I have a 2006 titan and its been an amazing ride (knock wood) i have 142,000 miles on her, so far it only has a volant cold air intake with a magnaflow exhaust system and have the E3 spark plugs installed also. I would like to get a little bit more umph out of her and was curious if any of those aftermarket performance chips are worth installing and which ones perform best in the titan. Are there any other aftermarket performance parts to consider along with the chips....are there shocks preferred over others ? not sure how this works but my email is [email protected] thxs ahead of time
