Update: I'm made contact earlier in the day with the shop that did the work and the owner provided similar thoughts as you all. I ended up tightening the bolts on the MSD and confirming connections were tight. Long term fuel trims now look much better (just under 5% at idle on both banks). Still waiting for the light to go away, but the tuner has been very responsive and I've sent logs to him to have a look. I do wonder if the spikes in short term fuel trim are something to be concerned about. They seem to occur when i roll onto the throttle. I will let everybody know if anything more comes of this.
Thanks
