Well, with perfect timing on THE hottest days in St. George's history, I weathered through the week to have PDI do their magic on our 1524.
I've already been running the PDI Super Boss Tuner, and now wanted them to install their intake and exhaust manifolds which improve airflow and heat handling significantly. This yields better and smoother hill-climbing, lower intake temps, and better mileage.
The guys at PDI are TOP-NOTCH, with great "Can-Do" attitudes, despite working in temps up to 115 degrees!!
Took 4 days by the time we ran a before and after dyne, installs, a couple mechanic repairs, and some lighting.
We ran the after Dyno in THE WORST conditions possible. The peak temps hit 115 as we pulled in, and even the Dyno brake system had overheated prior to running test. I recorded the whole thing on Facebook Live and received a lot of responses.
The numbers were great, with Dyno HP at 600 and Torque at 1638ft.lbs. The problem with the Allison trans, is once the Dyno applies full load at the peak RPM for torque, the trans will downshift, which messed up the readings which have to be taken in 4th (direct drive). Still, the numbers were awesome; considering all the negative conditions.
The drive home was great; smooth and strong and will only get better.
