I need a tune that will account for having no rear O2s and for an EGR delete. Could a mail order tune cover this or would I have to go into a shop and have them do it? I am asking because there are no shops within 3 hours of where I live. This is on a 04 GT with a SCT X2
Yes, any good mail order tuner should be able to account for those in your tune on your Xcal2. I know we do this sort of thing all the time so give us a call if you need a tune written and emailed.
