1. would I see much improvement in excelleration?
2. better to change just ring and pinion or the whole carrier?
3. what do I have to do to correct speedometer?
4. will is affect transmission shift points
5. recommend shop in Austin, Houston, Dallas area to do it!
6. opinion on rather its worth it, not going to race it, just want more get up and go from start engine is stock, exhaust is stock K&n air filter, 47,000 miles
