Most noticeable at idle. Unplug alternator and pulsating stops...bad voltage reg.... great. Looks like another plenum removal exercise, i don't understand how this could have passed... The guy checking it didn't seem like he know was he was doing.... should have taken it elsewhere. I haven't put Marcs chip in yet, need to get the car registered and through ridiculous emissions test. I need to get some miles on the car before I bring it. Feel like I am talking to myslf here but I can't stand it when threads are started but not really completed. After I get the car registered and the new chip installed, I am going to dyno the car with both chips and see if all the porting work and Marc's chip provided any additional HP.

Marc suggests to run the car through emissions with the stock chip, if possible. Also, make sure you run the test with the power key OFF or you will not like the result. When I had my 15K mile Z with brand new injectors and plugs tested, I didn't know that...ran it in full power mode and it failed MISERABLY! (BTW, the car was 100% stock at that time, except for those new injectors)
