Ford Raptor Forum

I need more info,
What Whipple setup? There are many options.
Who's Tune are you running.
What kind of cats are you running? Or no cats?
Did you install rear O2 extenders, or just had the rear O2s turned off?

So is a stage 1 3.50 pulley whipple 2.9L
hi flow cats from stainless works headers
Its a dyno tune from addiction motor sports in simivalley california
And its stock o2 sensors and all sensors are on

The cheap hi- high flow do not work well and won't last long.
You are better off welding the stock cats back on.
They are the best, you can go with Looks green cats but they are $$$ and doesn't flow any better than the stock

Also hi-flow cats require rear O2 spacers.

What does the Tuner say?
I don't know much about their Tune.
I hope they are not using HP tuning software because there isn't a reliable tune from HP Tuning for 2010-2014 Supercharged Raptor!!!!
