Need some imput

[doubleduce]

My last post was probably too long so here's the short version.

Thanks for the 7151 update.
Put the Xcelerator flow through muff., S&B CAI,and BBK 80mm TB on my '08 f150 5.4 running 89 octane.
SHOULD I:
a. add fuel to compensate for more air, how much and which peramiter?
b. use the 87 tune and add 2deg. global spark or 91 and subtract 2
c. am I totaly off the mark?
Thanks for any help,

anyone?

if your predator can monitor real time data, and/or log data.... i would run the 87 tune, then get your LTFT's dialed in...

after that, i would advance the timing little by little, monitoring for KR at WOT after EVERY adjustment....until you start to see KR... when you see any KR, back off the timing until it goes away.... there is probably a better way, but thats how i does it.

should be good to go after your feuling/spark is dialed in.

sorry i dont drive a Ford, but i hope i helped.
