The code3 is pretty easy to install and the crank pulleys take a little more time but can be done in 4 hours.
Tune is important.... I saw another 25HP gain with a tune..
Good luck....
Someone only saw a 7HP gain going from stock to a C3P S/C pulley? Results notwithstanding, logically that doesn't make sense - the C3P S/C pulley allegedly makes the same boost as the 178mm crank pulley options... so the power gains should be near identical. This seems to be supported by C3P's own C32 shop car's results - dyno-proven 21RWHP gain with just the S/C pulley...
I don't own a single C3P product, so I don't have any "skin in the game" here... just thought getting a 7HP gain going from stock to S/C pulley sounded a wee bit low...
