aem uego wideband a/f ratio help!
Ok so this is my first turbo rx7 its pretty much stock s5 swap, ive installed a Rtek 1.7 chip and a walbrro 255 with some (used) rc engineering re-flowed 720cc secondaries, right now its running off of wastegate control only even though ive got a dual stage turbo smart manual boost controller, besides the point, ive just installed a aem uego wideband and im wondering what readings I should be getting and if I should beable to hook up the boost controller and turn the boost up, right now with a shit gauge im boosting to the stock 5-6lbs range closer to 7.5lbs because of boost creep, any help could be useful

idle: 12-13
cruise: cycles around 14.7 boost: 10-12 if its leaner than 12 in boost, ticking time bomb your idle is a tad rich, probably because the walbro is overrunning your fuel pressure regulator |

So im wondering if the walbrro is even pushing the right fuel pressure because it makes no noise at all wich is strange from all the other walbrro ive had in various other cars |
