Not bad having electronic waste gate, just a different way of controlling boost.
Boost fooler, unlike the elbow, does not affect the boost made. It alters what the ECM "sees'" Plugs in line at the MAP sensor. Stops the ECM setting a CEL due to boost. Couple of different makers out there, I went w/ Quadzilla. Most programmers used will need one. Most modules, ex:Edge, do not (already built in the programming).
BD w/ CL= Bully Dog Triple Dog w/ Crazy Larry tune. Triple Dog and Power Pup both have: stock, tow (40'ish hp), performance (90'ish hp), extreme (120'ish hp). Triple Dogs only, have the option of putting a "Larry" tune in place of extreme. Some came from BD w/ Crazy Larry. The "Larry" tunes, (Crazy, Scary, Pedafile, Senator, the ones I can recall) are available to down load on line, free
. Larry tunes are in the 150'ish + hp range
. I can say according to my seat-o-pants-meter..
A lot of variables effect fuel mileage. If your in the 19 range, calculated by hand, IMO your in real good shape.
