What's next?

I never noted any performance difference running 87 or 93 octane in my 2007 Expedition 5.4 V8 in the 10 years I owned and towed with it.

I have a full tank of "92" octane in the 2017 this morning in preparation for a 2 or 3 hour tow tomorrow. 22 gallons of 93 on top of the 6 gallons of the truck's normal diet of 87 still in the tank. Will go back to a normal diet of straight 87 next week as the truck has more than enough power for normal driving with this fuel.

In my '16 Expy I have only run top tier fuel 91-93 and the truck drives like a sports car, very fun to drive and blows other vehicles away. As for the so called oil problem on the intake valves I heard this was only a problem with early engines and Ford made some changes. However every 20K miles I run Seafoam spray into the intake to keep the area and valve stems clean just incase....

I suspect you haven't driven a capable sports car (or even a Miata) in a long time. I've got a sports car and the Expedition is no where as fun to drive.

The 3.5 EcoBoost undeniably pulls harder than the 5.4 V8 especially if you can manage and produce an early turbo spool.

1985 Mustang GT....will blow the doors off most things on the road including a Miata. LOL

Make mine a 5.0

I had a 85 mustang GT. Although quick for it's day, at 210 hp, it doesn't even come close to today's mustangs/Camaros/ challengers. The weakest of those puts out 400 horsepower, the best 750. Our Suv's were never designed to be a canyon Carver. Especially a lifted four wheel drive version. You wouldn't expect a 400 lb man/woman to be a track star!

I have the JLT catch can and the JMS Boostmax. On 91 octane it will add 5 lbs of boost which translates to about 89HP and 81ft/lbs of torque. These numbers were based on a 2014 F150 3.5 EB on 91 octane. Using 93 octane might give you a little more power. I have it on my 2017 Expy and the increased power is awesome. Instead of 365HP and 420 ft-lbs torque I am closer to 450HP and 500 ft-lbs torque - almost like the Ford Raptor!

The great thing about the JMS Boostmax is that if you need any warranty work, you unplug the Boostmax module and there is no trace in the computer of it being reflashed like the SCT X4 tuners do. When the dealer sees a reflash they know you have a tuner and may deny your warranty claim.

Any pics of the jlt catch can install. I have a Moroso oil separator on my mustang. As far as I know catch can and oil separators are the samething, but others don't see it that way.

I know it’s been said before mike but great job on the engine cover. With the color it looks nice.
