i just changed the coil packs last night and what a huge difference in power, response it made...now i still get occasional blip in power..split second power dips...while getting on it on the highway..now ive read i should be using a one heat range colder plug (NKG)...im apr stage 1+...apr tells me to use the stock plugs gapped to .029, an audi tech says the one step colder, then a local performance shop tells me to use one step hotter...WTF...what is the answer with plugs and chips????
