Hi Guys and Gals, I am new here and thought I seek others advice on my planned mods. I purchased a 03 BA XR6T 4 spd auto a few months ago for what I consider an excellent price. I have approx $3K for my mods. This is a daily driver and wifey aint happy about that figure!! :argue: Ok, so here's my list: K & N Filter F6 CAI Monza Intercooler 3in MagnaFlow Cat, removed 2nd muffler Seimens 630cc injectors CAPA box Custom Tune Question on the injectors. Are these too big for my mods?? Should I go for the 440cc Bosch green tops?? Obviously, with the price of fuel, 'd like it to be fuel efficient as possible. I know it is a subjective question, but what KW should I possibly expect?? Anyone with similar mods got a figure? I don't really plan any future mods. But saying that, possibly a full exhaust down the track. The auto has been recently rebuilt, so I'm good there. Thanks for any input Ian
