I own an '07 turbo diesel truck; 6. 7; w/auto transmission. I use the truck mainly to haul my trailer w/about 8,000 lbs. in tow here in CA. We have some steep grades here & wondering if it's necessary to add gauges to monitor what's going on under that hood and the transmission. I plan to keep the truck engine stock. If so, what gauges would you recommend (EGT, boost, etc. )? thanks-
