Customer Question
I have an F-150,it...

I have an F-150,it had a k&n cold air intake,I switched that out for an Airade cold air intake,then I was told it’s running lean,the mechanic dynowed my truck,what I’m wondering is if I use my Superchips pcm programmer and everything gets erased from the synopsis,will my truck start running lean again,I have a 2007 F-150,5.4 liter triton 3 valve

Mechanic's Assistant: Have you checked the coolant level? Have you checked for a leak in the radiator?

I just replaced the radiator

Mechanic's Assistant: What year is your F150?

07

Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far?

The mechanic fixed it,but with the new airade cold air intake,I’m wondering if it will run lean,if I install a new pcm program with my Superchips programmer

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No,my mechanic fixed it

G​ood afternoon, I hope you are doing great. My name is***** would be happy to assist you with this today.

​So it sounds like your mechanic performed a dyno tune on the pcm, that tune will be saved in the pcm settings. If you use the Superchip programmer it will overlay the saved tuning that is in the truck now and it will delete the modifications that your mechanic performed. If you want to run the Superchip then I would advise installing that and then having your mechanic modify it again to eliminate the lean readings.

​Most Superchip programmers are calibrated to be compatible with cold-air intakes, so it may run it just fine

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

Jason V.Kirkland, WA

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.

BRNew Jersey
