Default Just threw a P0021 DTC code...Help!!

Like the title says I just threw a check engine light tonight and this is the code it pulled...I have had the car cammed for about 4 months now with no problems at all and today I installed the Steeda Economy CMVC Delete Plates and a wideband...I installed the wideband o2 sensor in the rear o2 sensor bung instead of welding in a new bung...dont know if this matters or not...but I have been driving the car for an hour or so and on my way home I threw this code...does anybody have any experience with this or know what it may be?!

Thanks

the dtc has to do with camshaft timing.

the pcm noted one of the cams in a more
advanced position, then what it was expecting.
this could have been due to a couple
different reasons.

i would clear the code and see if it comes
back.

yeah thats what I did...hopefully it doesnt come back...I do have the phaser limiters which I thought limited the timing to 20 degrees so I wouldnt think it would be too advanced but I could be wrong...

and yes I did get a tune for these but I got it a while back when Matt was still with BAMA and I think he may have wrote the tune wrong...the reason I think this is that for one the tune he sent me had the wrong PCM code...mine is CDC2 and the tune stated CDC3...also in the title it didnt say anything about my cams whereas whenever Doug would write me a tune he would always write in the mods I had...I dunno though...Ive read that someone had this same issue and had doug re-write a tune and it fixed it...I hope thats all it is...I have a Tillman Speed 93 All-Out tune that I should have in the next few days...I hope that corrects it

Yeah, I wouldn't do anything until I made sure the tune was correct.
