You'll see lot's of people stacking a pressure box with the TST in these forums. The TST on the higher settings really starts to stretch the duration out and the EGT's show it. Stacking a pressure box with it allows you to run lower settings while still getting the same or even more fuel into the cylinder. This gives you higher HP gains with shorter duration hence lower EGT's. Plus the two stacked together have a compound or cumulative affect. The VA on 100% is no longer just 40 HP on the top end. Due to the longer duration it's much higher (possibly in the 60 to 70 hp range). This particular stack also gives me over 270 possible fueling combinations. HP for any occasion and a beautiful towing stack that can run with the best of them when your playing hard.
