I have a 98 with 2bros slip on and K&N filter. Does anyone have a PCII map done for this setup? I tried dynojet but didn't see one with the K&N air filter... I did find a micron map with K&N filter, though, so I may use it. Also, I noticed some of the maps say with 93 octane and some don't say anything. When they dyno them and make a map do they try different octanes to see what works the best?
