    I just bought and installed DW 650 fuel injectors for better tuning over my stock injectors on my Harrop stage one. I was wondering if going to a stage two (80mm pulley) is worth it? If anyone has went to the stage two and has any information it will be greatly appreciated!!! I was wondering the pros & cons. Thanks in advance!

    According to Harrop Stage 2 gets you to 517HP and and 513 lb-ft torque up from 470 and 465 referencing page 3 of the Harrop tech guide thats been posted on the forums. Those are at the wheel numbers.
