Mythos

Ok so now that F***in Drive Clean had made all 88+ cars forever in the program, I need some advice.

After a tune up what upgrades can be done to the engine that would gain power and also would still keep in good graces with the money grabbing gov't. (yes i'm extremly ticked off with them, as many of you probably are).

Thanks in Advance

there are lots of things that you can do and still remain legal with drive clean.

Headers - make sure they are emission legal with air tubes
port plenum, higher flowing runners, hi flow base
exhaust - hi flow cat, 3 inch all the way back

These are things that you can do and remain smog legal.

When you get into heads and cam it doesn't become illegal but if you don't pick your choices well then you will have a very tough time passing every year which will be costly.
