can you tell me the best way to tune a 1.9tdipd 130 passat 5.5. going on bang for buck or price per horsepower. i've heard that they will go to at least 210bhp with turbo mods.
what is the cheapest and easiest way.
Look at giacusa.com - they show a chip that gains 22bhp, and up to 75 ft-lb with an exhaust upgrade (2003-2003 model).
They, or someone else, probably makes a decent chip for the PD.
Maybe Wetterauer, Upsolute?
