Now thats just not cool. Don't compare this board to LS1.com. It's not theyre fault that they are jealous.

 

Maybe RT was thinking that since the HD trucks come with such a larger upper pulley that one could install a larger lower pulley (say a 5-6 lber) on the HD and still end up with the same total boost level as say a L with a 2lb pulley (which is actually safe with a stock chip).

If I had a new HD I would go with a custom chip and start with the 6lb lower pulley and leave the stock upper. After all pulley size really isn't an issue it's the total amount of boost that counts when building a safe streetable setup.

Good luck with you truck, can't wait to see one click off a 12 second pass, as it is the trucks are already almost as fast as the motorcycles they represent .

 

Whew! It seems some L owners have some pent up anger at HD and want to take it out on a fellow f150 owner...real classy guys!

GT-40 GTS, you really can't depend on specific numbers from the L owners, because your computer code is going to be different. The generalities will carry over, but unless you swap to the same upper pully, and swap to the L computer, you might end up with some anomalies.

BTW, what is the computer code on the HD passenger door? CUX2?
