I have the 62mm pulley plus eurocharged tune, with Needswings intake, and as far as I can tell, it is quicker than my previous 181 crank pulley equipped car, which was quick.
I don't get on it too hard in 3rd and 4th, due to a possible lean condition (same as the 181), and plan on getting a larger fuel pump, and adjustable regulator, and dyno tune before fully testing it out.
Things have been known to go bad real fast when these cars lean out at high RPM.
