I just put a smarty jr on my 04.5. I have a stage II TrueFlow intake and a 4" straight exhaust. I have the smarty set on the 100hp level and i can barely drive it easy enough for it not to smoke. I am also only pushing about 33-35 lb of boost and i was expecting higher. I runs like crazy, but i'm afraid i won't get as good mpg as i was hoping. Anybody have a quadzilla boost fooler with a smarty jr? Any ideas???
