I want to understand some of the parameters in my datalog. How can I tell if one tune produces more power than another? Perhaps it's not that simple. But what I can tell by looking at parameters like spark advance, MAF lb/min, knock sensor, etc. What sort of things should I look for? I...

Anyone using the Steeda bumpsteer kit after lowering their car? Does it really do anything? I do notice at certain times- going over bumpy terrain that the car gets a little squirrely. I know bumpsteer is built into the car from factory but lowering may introduce more bumpsteer than is...

Hi guys, Is there a way to delete datalog config files from your X4? I want to datalog my tune with Lund and I have too many files on my device. When I add it, it just doesn't show up. Factory reset does not remove config files, only tunes. Can't find an answer on the interwebz.

Does anyone know why Lund sets the idle at 740 RPM? Just wondering why it is higher than the stock idle.

OK, so I've been running the Lund FF tune for a few weeks now, alternating E85 and 93. I want to switch back to my Bama 93 tune, but I'm not sure how much E85 is left in the tank. I ran it full tank e85, then ran it down to 5 miles on the dash, loaded up full tank of 93. Ran that down half a...

While I had my car in the shop to discover the source of my suspension noise issue (which they did) I asked them to put on BMR camber bolts so I could get some more negative camber. Here are the resulting alignment specs. On FR springs and shocks, CB005 in the rear. Front Camber (L/R)...

So I finally fixed the creaking noise coming from my rear suspension and just wanted to share with you all in case anyone runs into the same problem. I was getting this creaking/squeaking noise whenever I went over bumps or slow turns, entering into a gas station, etc. It had become very...

I have tried the E85 and have gone back to 93 octane gas. I want to datalog my Lund FF tune. Gas is running low now- should I put E85 back in and do the datalog with that? Or should I wait and do a datalog with 93 and then again with E85 in the tank? I'm thinking Lund will need an idle...

Anyone using a bumpsteer kit? With the BMR springs and now with the Ford Racing springs I am experiencing more fighting with the steering than it was when completely stock. Is a bumpsteer kit necessary for this car and does it really do anything beneficial?

Some of you may have been following my suspension mods. I am switching to FR springs and shocks in hopes I will like the ride quality better. Long story short, the work is done and the mechanic calls me- he says there's a squeaking creaking sound coming from the right rear. He narrowed it down...

Anyone know the spring rate on the Ford Racing Track Y springs? Did a search and couldn't come up with anything.

Question: if I want to switch from Konis to Ford Racing Shocks - do I need new shock mounts? If I remember correctly, the shock mounts need to be drilled out wider for the Konis. I assume this might become a problem putting Ford Racing shocks in there now.

How can I get a good 0-60 in my auto 3.15 car? I'm running A/S street tires. What is a good strategy to launch from a dig? Few weeks ago I floored it off the line with TCS off and spun so bad I hit the Rev limiter and went nowhere. Easing into it, the engine lugs for a second and will...

I had a funny feeling that my alignment has been off recently, took it to the Ford dealer for an alignment. Now I am having all kinds of issues. And I'm not sure if all of them are a result of the alignment but I know some of them are. I drive home in the rain and so I drove slow and had the...

Just got my Lund FF tune today for my JLT intake. Apparently they sent it to me last Friday but somehow I must have missed it. Initial impressions are good. The car is still adapting to it and I'm just running 93 octane right now. I'll wait til it runs out before I fill up with E85. The...

I'm considering switching out my BMR springs/Koni Yellows for FR shocks/struts and track springs including FR jounce bumper kit. Lately I've been tinkering with my shocks settings. Once I think I have it where I want it, I realize that I don't really like it. Full soft vs middle stiff...

What's the usual turn around time on Lund tunes? Is it actually 10 business days? I ordered a tune on Saturday direct from their website. No confirmation email, no order status. I did login and I see that they accepted my order and payment. Just curious why it takes so long, especially since...

I've noticed lately that my tires are following every groove and rut in the road, causing the steering to wander a little bit. Gripping the steering wheel with both hand mitigates the steering from wandering. But it feels somewhat disconcerting. Anyone else notice their car doing this? I have...

Anyone know of a great alignment shop in DC area? One that can work with aftermarket parts and lowered cars?

Strongly considering a Lund FF tune. Only have a JLT and a catback. My question is- how reliable is it? How often do you have to datalog? I want a tune that's just plug and play. Do you usually have to datalog it or do they usually come good to go? How easily can you switch back from 93 and...
