Midrange Power Help

[audiocableguy]

I have a stock 03 F150 HD. Off the line the power is ok for a 4dr truck. the probem is between 40 and 65 mph. What can I do to gain power in this band? Would changing the lower SC pulley be worth while? A Eaton to KB SC change was an idea, however I was told without some engine mods engine life would be short. This is a daily driver so reliabilty is a concern. next week a Diable Sport chip is going in. Any thoughts or suggestion would be great! Thanks.

Welcome aboard John. Changing the lower pulley and having the chip tuned for it will make a nice difference. I would also get a CAI and catback exhaust system. Check out

Both great vendors.

I'll move this to a forum made for HD F150s. :thumbsup:
