2002 4.6

Changed Timing chain guides, all gaskets and seals, everything on the intake manifold, valley pan, plugs, coils, power steering hoses, vanos seals, vanos solenoids and everything was said and done, installed the Dinan stage 1 tune. Love how smooth the engine revs and how relatively quick the truck is.

Love the shocked look on peoples faces when I open her up on the highway.

Super awesome. DIY or a trusted mechanic?

I have a great tech here, who did the job dor a great price.

I ordered all parts from ECS tuning as well as FCP Euro. Everything is OEM or OE.

Only sitting at 123k miles and loving it.

That's my dream scenario! I've heard of the Dinan stage 1 tune. How does the car drive compared to before the tune?

Snappier when you tap the gas. When I’m in “sport” mode and let go of the gas, I get some nice burble.

I haven’t been paying attention to see if the rev limiter did in fact move out a little bit.

To me, the price point of the tune warrants its use even if the gain is minimal.

I wish I live in VA now! LOL

A shade over 130k
 

The E53 is doing daily duty ferrying the kids around town for summer activities and shopping. So, to address the slight roughness that INPA showed, I replaced the MAF with a Pierburg that I bought on Amazon. Runs smoother and, I hope, a little quicker.

Since mid-May the SES light has been on. There were two codes, one for the aux fan and one for the tank vent. Aux fan was solved by cleaning the connector and putting some dielectric grease. Ordered a new gas cap from FCP which, very promptly, fixed the tank vent code.

Next is replacing the o-rings on the fuel injectors. I also got the top rubber insert for the windscreen as replacing the glass, that has been cracked since 08 or 09, should really be replaced soon.

New front brakes. Gotta do the rears in couple of days.

Had more time to pack on my return trip. It's amazing how the Packout fits as if the e53 was built around them.
