i did not find any thread about it but i was thinking about a mugen chip is it worth it and does it **** your engine up or is it good

 

no rev limit has been known to "**** your engine up".

 

what engine/ecu and whoever chips it for you could add a rev limit... simple...

 

all the chip is going to do is remove the rev limit (bad idea) and increase the amount of fuel, and advance ignition timing. It may help, it may not, but your gas mileage will most likely suffer. Your best bet is ghettodyne for a cheap upgrade.

 

The "mugen" program that everyone is selling is a open loop program. meaning a wide open throttle only program. Fuel economy is crap. and horrible for daily driving at $2.00 a gallon. but thats my opinion, try it out but dont spend more than 100 bux on it.
