Sorry, no chips for this one, but you can have the computer redone by someone like JET--you send the whole unit to them, and they do their magic in their shop. Headers are probably the #1 power adder for this model (because of the factory's absurd, power-robbing crossover pipe)--they add some power alone, but more importantly, they make other mods work better by improving the total airflow potential. That being said, I have looked into this quite a bit, and nothing you do will result in any great gains. If you did headers, high-flow exhaust, a cool air intake, and the computer, you'd have about $1500-2000 in mods (the headers are expensive) that MIGHT give you another 25-30 hp. Given the pitiful starting point of the 3.0 (105 hp at the wheels on K&N's dyno), that's not going to help much. This is why you see so many articles about engine swaps with this model--just upgrading to the next Gen's V6 makes a big difference, let alone more radical solutions like V8's and such.
p.s. That pic is quite interesting--the "magic hour" lighting combined with the shallow depth of field makes it look like a toy (the little kind) truck on a model railroad display!
