Uprev Osiris tuning questions

For both. There is a lot to watch for. Like Chris said, once you start getting into ignition timing it can get very interesting. As mentioned above, all the motors are different as are tunes should be. Some are "Lean and mean" and others like "Fat and rich". Your tuner will hopefully find the winning combo for you. He might need to make it rich through some RPM ranges and then lean it out in others. You should be good with a "E-mail tune" but to get all you can, live is the way to go. Having said that, don't expect a huge difference in the two tunes. You're only trying to squeeze the final ponies out of your engine. Another thing to watch is the tuner himself. Some like it on the "Cutting edge" and some are "Safe". Hope it helps and let us know how you make out and who you deal with.
