This is why I do a compression test before I tune your car.

Lots of people say, "Oh don't worry about a compression test". Half the time I find platinum plugs, old corroded NGKs, or even worse. :barf:

This explains the 4500rpm stutter, the customer was complaining about.

Please let me do my routine checks on your cars when you bring them. I can sleep better at night knowing its going to run as its supposed to. :D
 
Man I hate those stupid plugs. I replaced these in my gf car because had a misfire. I knew why soon as I pulled those out. Sure enough the proper plugs fixed it.
 
Yeah proper ngk plugs is a must anytime your looking at tuning, or doing a dyno run on your car. spark plugs are just too cheep an item to not carry a spare set of.

my recommendation is if you go to to have your car tuned on a dyno, or are tuning your car 1 or 2 spare basic ngk/denso spark plug sets, also don't forget to bring a set of colder spark plugs too, proper spark is a must during fine tuning, who knows what your plugs look like on your not tuned car, going to said tuner.
I personally would use brand new basic Mitsubishi recommended copper ngks.

thank you turbodssm90 for bringing up a good topic often overlooked by vehicle owners.:thumb:
