Ok so I have 06 F150 Screw 4.6 w/ a flowmaster and K&N CAI. I was running level 2 and just started using level 3 with 91 octane.

Anyone have any suggestions on my current setup. Do I need to change my Fuel or timing? Im at about 300-500 FT above sea level.

Level 3 91 octane
WOT shift: 1-2 @5075 2-3 @5075 3-4 @4800
Firm: 1-2 +6, 2-3 +6, 3-4 +3
Rev limit: 5400
Tires: 2440
Timing: 0
Fuel: 1.20

 

At your altitude, I've seen good results with taking the WOT Fuel to 1.4-1.5 and maybe toss in another .5 degrees. Everything else looks fine.

Take care.

Nice. Thanks for the input.
