Tune problems I would imagine. 230/236 isn't a small cam but certainly isn't huge either. I would expect a little surge but, you need a better tune it sounds like.

Not a correct tune. Do you have front O2's installed? Did your tuner disable closed loop?There is usually a 'closed loop enable' field based upon coolant temp. If it's set real high, then the car never goes into closed loop. Not being in closed look prevents the computer from making fueling adjustments.

SD would be ignoring the MAF signal (which corresponds to a measured amount of ingested air) and relies completely upon tables in your calibration.

If you know that the tuner disabled your O2's, does that mean you can read your calibration and post it here?

after my first tune ..car started to throw o2's codes ..then i went back to the tuner .. he mentioned that o2's must be disabled for better idling but noting changed since .. running rich at idle and bucking on low rbms ..

i replaced my plugs & wires ..
cleaned my maf and TB

and still same issues..

its 100% tune. my cam specs in sig. surges twice every startup, then runs fine. retune

A 230 236 on a 112 if done right should idle almost like stock that cam should be smooth so either something in the tune or sensor issue Hookup wideband would be your best bet.
