[Longshot]

Dominic is no longer doing email tunes (at least for now) so I doubt he'll respond. A wideband is nice but not necessary. Dom tuned my car very well without one. If your only additions were IC hoses and MAF tube you do not need any tuning for those. I guess maybe you could try Ron, (dumdum) on this site. He tunes his own vehicle via opensource and is very knowledgable. I don't think he's "open for business" but you may want to PM him to ask. There are others that do custom maps like pdxtuning, surgeline tuning (Tim Baily), etc. You may want to try Surgeline as I believe he's still active doing internet tunes. He will be a tough guy to get a hold of though as I've heard from many.

Either way with those mods you can run your base map, but it will never be as good as a tweaked one.
