More Smoke

[Bobbys Big Red Rig]

I have a late 99 7.3 powerstroke. Phoenix chip with Whisper, Stock, 65 Towing, 80 DD, 120 Race, 140 Smoke Show. Stock injectors, 6637 intake, stock turbo, stock waist valve. What mod can I do to get more out of smoke show? Puff is OK but I want a smoke show. Other than putting my foot in it is there a way to get more out of it. Would not change my PHP for another tune because I love the way it shifts and The PHP family are good people. Just want more smoke.
