I pulled my spark plugs today and all the tips where really white....I just did the headswap and put longtubes on about a month ago now...does the white tips mean the car is leaning out and would this affect the performance of the car???I plan on getting the car dyno tuned next week since the last thing I want is to burn a hole into a piston....my car is a 98 GT by the way with 59000 miles on the odometer

I noticed the same thing. I don't have a headswap, but I do have longtubes. I change to copper plugs about 3 weeks ago and my old plugs were pretty much all white. I am going to pull a plug or two this weekend to check on the new plugs. I am curious as to what is causing it, if its the headers, then I guess I am going to have to pony up and buy a MAFburner....
