Going to purchase a wide-band for the apex..any suggestions which to go with/stay away from. What have you guys found for air/fuel ratios? Do I even need to get one!

You should have posted in the Turbo/Supercharger section, most of the boosted guys runs a wideband.
FJO is expensive, but probably the most durable and best quality there is, warranty is second to none.
Innovate (I run the LC-1 and XD-16) have a great system at a lower cost, not the same build quality as FJO.
Both systems are accurate and will give you the info you need when tuning your sled for performance.
If you are going to run higher boost than your turbo systems default pressure level, I would strongly recommend you buying one of these WBO2 systems.
You will also need a quality boost pressure gauge and a good boost controller, electronic or manual. I run the Hallman Pro RX MBC in my sled, and so does a lot of other guys, with success.
If you decide to go up on boost. Set the target boost level and finetune AFR and clutching accordingly, then run your sled at that boost level. Running different boost levels all the time throws the clutching and AFRs out of wack. What works on 16 lbs does not at 12 lbs, been there done that, used to run a high/low boost switch, worthless. I'm now at 16 lbs, have been there for 1 1/2 season, I'm not touching the MBC unless I'm forced to

This for a stock Apex. I'm running a PCIII fuel controller, moded airbox and ignition module. I would like to see what my A/F is all the time.

Most AFR systems will show you real-time data, both as a bar graph and in digital #s with 0.1 AFR accuracy from 9 AFR to 21 AFR. The FJO and the Innovate is the ones with the fastest response time as far as I know.
