Question for the TBI experts, if i have deleted the cats on my new exhaust system have i messed up? My truck originally came with an up stream and after cat oxygen sensor according to what I have researched so far. I did have a bung installed on my new collector but no provisions for the one that would have been post cats. Whats the right set up? i got a hot rod buddy that keeps telling me to ditch the TBI and go carburetor and get a simpler set up. I am considering this but would love a 20 buck fix of an o2 sensor to be all I need. Yes I think 15 mpg is going to be ambitious. I am starting to temper my expectations. I will sort out the small issues I have now but that may be as far as I go with this small block. Starting to think about 13 mpg from a 454 rather than 15 mpg from a 350. That may be frustration talking but however far up the mpg hill I climb, a inevitable lift and the 35 inch tires will knock me back.
