220, 221...whatever it takes!
Seriously....I need the real answer....
Over and over, I have received conflicting info on which lower pulley is safe for me...
Some say 4lb, others say 6....because the HD has a different pulley than the L on the SC....a 6lb for the L is the same as a 4 on the HD....
Don't know 'bout yall....but I think the extra 2psi would suck-bad if that is not right.....
For those that need a refresh.....
1997 F-150 4x4 3-door 4.6 Vortech SC turned
1997 F-150 4x4 3-door with a 2003 HD 5.4 SC Transplant in front of a WAAAAY expensive Art Carr 4R100. Cluster and computer are 03 Lightning. C&L uppers, Accufab single blade, Lightning MA, SCT2 Flash
So....whattadillio?

A 6lb pulley in the Harley over stock is okay. The stock tune is pretty damn good up to that point, anything after that... no dice. I've tuned plenty of them (HD's) at 6lbs over stock and while there is extra power to be picked up with tuning in stock form the A/F ratios are pretty good, and sold a ton of 6lb pulleys to Harley guys who left the tuning stock. You're only getting about 4lbs actual boost over stock with it because of the upper pulley, and even the Lightning can be run without an aftermarket tune at with 4lbs over.

I have an SCT2, so throwin code at it should be a non factor...
Thanks for confirming about the boost difference. Keep in mind, I'm running an L computer, but I think it is going to see it as 4?
