no flange, but if you really want i canweld one on. its prolly best to have it done by a muffler shop cause idk how it will work for you or how far to place the flange. id really need you to come to houston for me to be able to fit it.

well iv got a couple of updates on my tune for those that havnt seen my other posts on other threads....
I found the cause of my stumble issue finally....i had the wrong slave version running on my fic. Apparently z104.hex is the file you need to flash your fic with for all scion tc's. So tunes are running alot better. I also used Jons original (first gen...lol) map and set the 02 table to map and changed some of the values on no load portion of the map to something a little leaner and did my best to match the fuel map with the changes. everything was going good until today and it seems that my afr's will go lean at random. It will stay lean for like a couple of min's while cruising but then go back to my target afr.....i tried to tune my idl and cruise to 13.8-14 and got pretty close but its still a work in progress and im still learning. iv got my wot @ 12psi running about 11.9...sometimes it will peek at 12.1 so ima add a little fuel to the upper portions of the map i think and work more on my 02 map. Maybe i can try and match the fuel map a little better to my 02 map and keep those lean conditions at bay...... If anyone has some tips please help a brother out...

Oh yeah, lol. I changed my tune around a lot, but that's because I took out the O2 sensor, so now I'm stuck in open loop. It runs great, but I have no fuel cut off on decel anymore lol. It sucks for gas mileage, but it sounds awesome. It pops and gurgles on decel :D.
