MATE did we change cams lol 3 times , and pipes we tryed 3 combos with all cam combos , we tryed so hard to get the torque up , in the end it got the 1308 cam , 590Lift 300deg and the SW race pipes , the big pipes lost a bit down low around 15ftlb , they were better after 5000rpm all the way to 7500 but as a road car the small pipes had to go on , also the big cam just did not work in your EFI combo.
