big name tuner with best drivability?

[Chris@Lethal]

Always have used Lund Racing and never had any issue with drivability, even on our s550 with 850rwhp.

I didn't realize you had to use a laptop to datalog with the x4. That may easy for a tech savvy guy, but it sounds a bit complicated to me. Especially when compared to logging with the ngauge.

Side note...when would you need to perform a crank relearn? Is this ever necessary when swapping tunes?

You don't need to have a laptop in the car each time you are logging with the X4. My Ecoboost Mustang was tuned by Torrie at Unleashed Tuning. He sent me a config file that I loaded on my tuner and I logged from that.

I have a nGauge w/ Lund tune. If I had to do it over I would have went X4 and likely VMP or AED. Not a big fan of the nGauge being locked to one tuner. I had reservations going in for that very reason, but with the praise Lund gets on here I took the chance. WOT is fine on the tune, part throttle felt better stock. Lund tune too jerky for me.

That's what I'm going through now. My Lund tune is feeling too jerky.

The ngauge datalogs with the push of one button on the device. Once a log is complete, you can either remove the sd card from the device and plug it into your pc, or download it from the device to your pc using a micro usb cable. There is no software or additional drivers needed.

This is how I understand it anyway. If I'm wrong, please correct me.

It a crank relearn is neede each time a tune is loaded and the ngauge does not perform this...is there an extra step in missing?

Honestly, I'm not sure. I was asked to do it a couple times when datalogging with Shaun.

Don't you guys partner with Lund? I'm not saying he sucks, but you guys do have a business relationship. I can't imagine you'd post on this thread agreeing with the jerkiness or flat midrange comments.

I don't know if you would consider JPC Racing a "big name tuner" as they don't really do email tunes, but Kevin MacDonald had my cammed, monoblade setup running amazingly perfect with great driveability.

The car jumps rich when it does it, then goes back into stoich. I pointed it out on the log and was told "looks normal". Sent one log on pump, one of E85. No revisions, said looked good other than some knock up top, try better fuel (on the pump log).

I'll go ahead and say it, if the initial tune is the final tune with no revisions, what separates that from a canned tune? I think Lund is really dependent on whom you get as your "tuner". John jr and sr definitely know their shit, but some of the other guys I am not sure of.

OK I discovered I am getting this noise from my right hand side cat area:

Seems loudest around the flexi joint, like dried peas in a tine or metal filings in a tin.


Could this cause my false knock? Am guessing cat is failing or an internal weld has come lose and is inside exhaust pipe.

This is my reservation as well. Seems 90% of lund/ngauge guys report they send their logs to Lund and are always told it looks fine. Maybe they really are that good? Or is this like when you know something is wrong with your car but the dealer tells you it's 'normal' because they either don't know what's wrong or don't want to put forth the effort to find out?

You have aftermarket headers, right? What brand?

No they are stock!

Only modified part of the exhaust is catback which is a Corsa Extreme and it has a solid ding ding.

But the RHD stock cat, particular at the flexy joint makes that noise like metal shrapnel in a can, so either cat has come apart inside or an internal weld.

I ended up going with Lund and I'm pretty happy. I did talk with Shaun at AED and Rob Shoemaker last week. They both seemed to know their stuff and I really came close to going with them. What ultimately drew me to Lund was two things...the package deal discount I got through Beefcake when I ordered some other parts, and Lund using the nGauge. I just like the nGauge more than the SCT X4. The drivability from Lund's tune is as good as it was stock. Their were some minor quirks with the stock tune that I was hoping a tune would get rid of but it doesn't look like it will, but that's no big deal.

The car *feels* like it has an extra 75 horsepower but I suspect the majority of this is due to the increased pedal sensitivity. Whatever it is, the car feels much less "neutered" now. Ive always thought the car felt a bit "tame" for a 400+ horsepower car but now it feels like I always thought it should have from the beginning. I am going to ask Lund to tweak some minor things....the e-fans seem to run a lot more than I feel is necessary and the idle seems a bit higher than I'd like. I suspect these will be simple fixes and I'll talk with them about this when I send back some datalogs. I doubt they will feel the need to change much if anything performance-wise. The nGauge shows the car is always adding spark, usually around 2* at WOT and up to 6* at other times during roll-on throttle or general driving. SO I'm happy to see no knock like other gusy have reported. Maybe we just have better quality fuels around here. But overall....I'm very happy.

I was able to get Jon Jr to adjust the throttle settings more to my liking. Car is much better behaved now. He also took the time to swap my tune over to the 16 GT PP strategy so rear diff temp PID would work. Big thumbs up from me for him.
