Has anyone reflashed their 3.0SC V6 aka Tune?

Gotcha. I probably just need to datalog next summer. Thinner air here, plus we're stuck with 91 Octane. Car feels very strong now that its 20 degrees.

I replaced SC water pump with higher flow model Bosch. So not sure it is a good example of heat soak.

Has anyone had their supercharger ported? From what I can gather it’s about 30-50 hp gain and 40ish ft/lb.

VAP is now offering it, and there are a couple other companies as well (Kong performance, JorkerZ); they seem to be pretty competitive in price with each other.

I picked up a used supercharger off FB marketplace for $150 in great shape; seems to be low miles, very little play, hardly any wear on the snout shaft, and coating intact on all the rotors.

At 120k miles I’ll be doing a lot of maintenance (crossovers again, tstat, spark plugs, attempt to walnut blast the intake valves, etc.) and figured I could send this supercharger off to be rebuilt and ported so that I can swap it while everything is off.

Well i got the tuner, pulley and belt. I have a mac so i had to buy parallels and run windows to get the flasher to work. Kind of a pain as there is a specific sequence of things to get windows to identify the tuner. Not exactly straightforward, but it can work. anyway, i went through the process - note that the LR4 is not one of the cars on the tuner, it is instead the JAG scv6 that you use to pull down your eco file. Pretty easy. emailed stuart and chris the results. They are definitely attentive and respond quickly. i had them turn off the ECO feature and they sent me three tunes - stock, no pulley, and pulley. I will get the pulley installed on friday. for now i am on the "stage 1" if you will. Definitely peppier. more torque down low. engine feels very lively and punchy. and it pulls much faster and harder through the revs. It almost feels like it is running away from me and I have to back off the throttle much faster. Going to take some adjusting to i imagine. overall I would say that this tune level feels like the truck should have come this way from the factory. i know LR likes to differentiate off the same platform, but it is a shame you have to void the warranty to do what the engine is capable of.
Should be pretty significant difference with another 40 or 50hp after the pulley. I am quite interested to see what happens to my MPG after this and after i calm down to normal driving again.
I average about 13.5 before the tune. Lots of city and driving 80mph+ in the mountains.

Hello I was wondering if anyone has the cds for sdd software for the old wds tablet? I obtained the software about 12 years ago from a member but I lost them. I

You can also get a larger supercharger from VAP.
