Question on your O2 mod, I just had a set of OBX LT's and magnaflow 94106 cats installed. I just had my CEL light come on the other day. Your write up indicates it is for going cat-less, since I have high-flows on could i get away with just one NF drilled out per rear O2?

Those non foulers for your 02 sensors are interesting. Im guessing it keeps them out of the condensation in the exhaust? Do they not have to be in the direct exhaust flow? I may do this as im going to replace my o2s anyway.

How are the OBX headers I plan on buying them too, what else did you do with your exhaust besides Magnaflow?

Hey Gotts,

Who wrote your tunes for the XCal? Did you say you have the 93 performance, 87 performance, and 87 tow? What kind of difference did you see between the three compared to stock? I currently average around 14 mpg since I tried out your intake mod, which is about 1 mpg better. Nice idea. What kind of mpgs did you get before the tunes and after? And, what kind of mods do you currently have on your truck? Sorry for all the questions, but it seems like everyone who posts comments about the tunes has the newer style trucks, so it doesn't really relate to me. Just trying to compare apples to apples.
