need wide band asap sounds like your not running 14.7 afr at part throttle and a clogged cat might not throw a cel for a while I got 18-20 mpg driving on group drives and 24-28 highway it varies on conditions running air the hardtop gave me 1-1.5 mpg on a 500 mile trip that was with an emanage and rc 650 injectors will be curios to see what I get with the aem and id 1000's good luck on finding the culprit I assume you are running 91-93 octane need to ditch the stock injectors and the supplemental injector that could be your problem if you have aem run the id 1000 they are great

Yeah. Why running stand alone and fmu and stock injectors. Scrap the fmu and stock injectors and get Bosch 900,s. Then returned with someone that knows how to tune. Wot power pulls is like ten percent of the tune lol.

Car has been tuned, I was going to order the ID1000s along with a 13 PSI pulley. Guess it probably does have to do with a tune.
Company called H1 performance did all the work. Tuning cost was $500. Think ill change tuners lol. It put 352 at the wheels.

thanks 
its running a walbro 255 pump. that freaking whine is annoying the hell out of me... my EK had the same pump but was in tank under the seats so it wasnt as loud. i have a set of RC SL4-650 that came off my EK build. would those work for this setup? or are they too low of CCs?
