Hi guys,
I've finally put my '07 RSVR on a dyno and it turns out I'm running quite a bit rich mixture(see attached picture, sorry I've rotated it in my PC but it still wouldn't turn after I uploaded it). It's most likely due to the fact that I bought it in St.Louis, MO area (elevation 460ft) and I live in Wendover, UT (elevation 4,400ft). The mechanic who did the dyno run told me he can adjust it for about $350. Now my question is if it's worth it since I'd be gaining maybe 10 - 15 HP and probably 7 ft/lb or should I consider buying a PCV and download the right map? I have stock pipes but I've drilled out the cores to turn them into a straight pipes because it was running a race map. I've been told I should first replace/wash my air filter before I do that, and change spark plugs and that should help my air/fuel ratio but ultimately I'd like to install PVC so I can change it back when I move to a place with lower elevation so I don't have to pay another $350 to have it changed back.
What do you guys think?
