Here's a stock car..just a tune.
The 415hp base and even 450hp X50 have a TON of left over power in them, OMG. They're so moddable and the gains are ridiculous.
Have you seen that engine apart? When the 996T came out the local dealer had a launch event and they had a factory guy there with an engine open, and wow, the quality is amazing. Porsche went to town on the car, seriously. The amazing part is that for the price of a used Cayman you can build a car that will run with or leave behind a new Z-06 or other high dollar zoop-er car.
