You can play with turbos, exhaust, boost, etc all you want but it won't make any more power until you feed the engine more fuel. You can get about another 20% power increase from the stock injection pump, beyond that, it's time for 7mm pump elements a la Myna Diesel. (read: $$$$) The ALDA is still limited by the internal full-load fuel stop, richening that way will increase fuel at low RPM, but will not increase peak power. Increasing boost beyond what the engine can use just makes heat, not power. My engine makes the same power at 12psi that it does with 18psi, so I left the boost at 12psi.
Side note... I've got my EGT probe in the #1 exhaust port and have seen >1450°F temps, at which point I chickened out and lifted. That was under extended WOT. Don't try this at home, kiddies. Under normal driving it rarely exceeds 800-1000F.
