Hello how is everybody?

I just purchased a lightning today. It is a 2000 with 30,000 miles. I have a couple of questions I was wondering if anybody could help me with.

First, the boost is reading past ten to what would be twelve at WOT. The truck is supposed to be stock and it appears that way. Is it normal to read this much boost and is it going to hurt anything? I live in Iowa and the temp. is about 40 degrees.

Second, When I got the car the check engine light came on and two codes came up. First it said O2 sensor and the second said max boost or max speed. Then he cleared the codes out and said everything was fine, now the check engine light is back on. Any ideas what these can be? The truck runs real strong right now. I'm new to the Ford Lightning so I would appreciate any advice.

thanks skelly454

 

The stock gauge is junk and totally not calibrated.

FYI- You never have enough boost

 

Post a pic of your pulleys. We can tell you whether it's stock or not very quickly.

 

Hey thanks for the advice guys. I'll see if I can get some pics of the pulleys. Well my check engine light came back on so I took it to Autozone so they could run the code. It came back p1131, something about air fuel ratio. That's all they could tell me and told me to contact ford. Any ideas on what that could be? Also do you guys run the recomended 5w-30 oil. What kind of synthetic do you recomend. Thanks again

check to see if you have the stock 80mm MAF or the 90mm MAF that came in the 01+ L's. Your stock gage isn't very acurate but you may want to pull the blower and check your intercooler. If the truck was modded and ran hard in the beginning you could have oil coating the intercooler or your rotors could be flaking and partially plugging the intercooler. There is also a rubber boot on the back side of the lower manifold that rots and lets unmetered air in/out, you'll have to pull the blower to check it but something else that is common on these trucks.
