There are very few places that tune LT1s.....I say your best bet would be to invest in a wideband O2 sensor, and keep tuning it yourself on the street and on the track.

Your stock O2 sensors are designed to work best right around 14.7:1, but that's not optimal for power. Since you are trying to get the A/F lower than that, your stock O2s won't be very accurate. This is where the wideband comes in.
