February 26, 2007I have all the external mods you could put on the regular PT Cruiseer, intake, wires, coil, spark plugs, power tower (Helix), JET chip, exhaust, etc. But still after all that, I think my Cruiser is not runing right, so now I need of some assistance. I plan to buy some cam gears and a fuel preassure regulater, so that I could go and Dyno tune my PT. The main thing is that I am not that familiar with this area of dyno tuning, also I herdt that I need a piggyback to tune my car. So for everyone out there that is interested in this and knows anything about this please let me know, I am new here and I am trying to learn from everyone here.
