Curious why you changed from the 9G90 to the older style 9A90's?  As I understand it the G series has the best spray pattern, so the A series won't give you as good fuel mileage or power.  Good Luck, TomC

Tom i have a 8v92 475 hp i have changed the turbine housing and ever other thing to do away with the smoke  i have had it worked on at SO Diesel, Williams,Las vegas freight liner and S&S in Houston and after about 5 grand later i putting in back to the specs on the valve covers I never used the extra 30 hp so i won't miss it and i got better mileage with the 9a90 injectors than with the 9g90 i think 445 hp will be enough for me because i do not need to be anywhere now in a hurry but thanks for asking

Personally, I would change to 9G85 if you want better mileage.  Will still have 420hp.  Good Luck, TomC
