The SRT-10 A pillar is a perfect home for a combo-type EGT/Boost meter. A top quality digital guage may improve precision, accuracy, and speed. Rapid transients such as boost pressure and peak exhuast gas temperature are captured more easily, and in my opinion, more accurately in the absence of physical limitations imposed by ballistic metering.
Even so, we are much better off with any guage (digital or analog) which reveals real-time data while under way.
I have used an A pillar display of EGT/Boost for about one month now, and find the info indispensible for monitoring performance, and establishing baseline numbers for comparison to future values resulting from enhancements/modifications. If you think high quality data is good for your truck's well-being, consider buying equipment above entry level pricing.
In both work and play, I always advocate that better information and better communication to improve the way we live!
