Mail Order Tune Accuracy

PM-Performance · May 14, 2019

My car was recently tuned by Brandon at Lund.
Was about the most simple task I have participated in to be honest. My 93 octane tune was done on Rev2 and Race gas tune done on rev 2. I have no complaints

Do you provide remote tuning services for 2005-10 Mustang 4.6L 3v applications? After looking over your website, I don't see anything listed for the 2005-10 4.6L 3 valves.

No sir. Far too many issues with aging components.

Lund tuned my Whipple 2015 5.0 making 850rwhp for 2 years. Drove that thing all over the east coast with no issues

I have had a Lund mail order tune on my car for 7 years with no issues. Recently got a Gen 2r and supporting mods and decided to get a full tuning session. Super happy with the results. Took 4 revisions of the base tune to get it dialed in perfect. I daily my car so drivability was paramount. i will continue to use Lund Racing as long as they continue to make me a happy customer.

Been pretty happy with VMP. Car is still together, and I get the carbon out quite a bit. 21lbs, 93 octane, at sea level, that's saying something lol.

First tune ran good (686/700), data logged it on my buddies dyno, got a tune revision back (haven't hit the dyno ), and found out I was running out of fuel pump up top. ID1000's made it safe though, still haven't boosted the pumps, but it was nice of them to tell me.

Mail order tunes are typically on the safe side, accounting for a tank of bad gas here and there regarding timing. In short, they lower the timing up to a few degrees when compared to a dyno tune. Seems to be pretty common to pickup 20hp~ or so with an actual dyno tune.

One thing you will notice and which may make the car feel wrong, is colder plugs. Your car has two fuel loops, one for warming up (open loop), one once at temp (closed loop), could be wrong on names but think of it as a choke. It's not my first car with colder plugs, but i've noticed when the car is open loop warming up, it drops RPMs really fast, basically lose all rpm's between shifts, can even feel it breaking up a bit in the lower rpms. Once she is warm though, perfect. I think this just comes with the territory of colder plugs.

Being as your GT500 is factory supercharged, I'm assuming that Ford both installs and requires running one degree colder spark plugs? If not, then my apologies. At any rate, I have the Saleen series VI supercharger on my 2006 GT. What I do know, is that Saleen requires running Autolite HT0 spark plugs which are one degree colder plugs. Needless to say, I have never encountered any of the open/closed loop related issues you describe in regards to losing all RPM's really fast between shifts nor breaking up at all in the lower RPM's. IMHO, if you're encountering these type of issues? chances are that either your spark plugs are not properly gaped or it's a calibration/tuning related issue that requires a revision regarding the open/closed loop parameters. Anyhow, just saying.

I ran an email tune with the "kit" I purchased. Went to the track and melted 2 pistons.
Built the engine with a 1200 hp kit. Multiple datalogs and revisions. I said I want to go to the dyno a do a pull because that's the service I paid for. THe tuner said no need to and your wasting your time and money going to the dyno its perfect according to the data logs. Went to the dyno did 1 pull and emailed the tuner. They responded DO NOT RUN the car again. Revised the tune and picked up 80 hp safe afr.
ON the street I cant safely do a full 4 gear pull data log. That in the 150s mph. DYNO EVERYTIME is my opinion and experience.

06torchredgt · May 18, 2019

It always makes good common sense to have calibration tunes verified on a dyno for both piece of mind and assurance that all parameters are spot on. Nothing against data logging, however as mentioned above, how can a full 4th gear pull really be done safely on the street in order to get an accurate data log? Therefore I agree that data log runs/pulls should be done in a controlled and safe environment on a chassis dyno.

4th gear 6500 rpm is 127 mph. Just saying there are plenty of places and times that can be accomplished safely.

Well perhaps in Italy there are, however, here in western PA U.S.A there are not. We have very strict traffic laws that are enforced by the PA state police on our interstate highways when it comes to driving 10MPH+ over the legal speed limits.

Sounds like a Prius is calling your name.

Never said that I always obey the traffic laws. Just saying they're heavily enforced. As I'm quite certain they're also heavily enforced in So Cal as well. Also FYI, I've never owned nor will I ever own a ****ing ricer, neither foreign or domestic. Whenever I have the need for speed, I take my car to the track where it's legal!

Thing is, unless your car has widebands, you need to be on a dyno, or rig one up in your car to log from it. Won't do you much good otherwise. I don't know why you can't log in 3rd gear on the roads either, unless traction is an issue.

I know with the gen2r, 3rd can be pretty sketchy. Hell, i broke loose in 4th the other morning. Granted, morning, but still.

As for Italy, the roads are so shitty that it was difficult to find a road to do a WOT 4th gear pull. Seriously. Never come to Sicily. But had no issues finding a road in Washington, Colorado, Texas, Utah or Oklahoma. Maybe Pennsylvania is a small crowded state like Massachusetts or something?

You're absolutely spot on, as my 2006 GT doesn't have widebands. IIRC widebands weren't available from the factory until the Coyote 5.0 4v debuted in 2011. Of course I could always rig one up, but even so, it would be difficult for just one person to keep track and operate the wideband while keeping their eyes on the road in front of them at the same time. Therefore it just works out better for me personally to have my car put on the dyno whenever I need to verify a mail order tune.

You're definitely spot on about PA being a crowded state. In fact, afternoon rush hour begins here at 3PM lol.

Im closer to 160 with my gear, tire and rpm in 4th

Time to regear. I'm assuming you have cams. Your engine will be a lot happier with 3.73s. I'm contemplating going to 4.10s from 3.73s

I am in PA. We do highway pulls on the regular. I get it though, its not for everyone.
That being said I have been getting my cars street tuned for many years and dyno tuned at times as well. Just depends on the tuner. But street tuning tends to be more accurate to actual conditions. Dynos that can be loaded do this as well, but you can see a diff in the cars parameters from a non loaded dyno to the street. I know i have in my cars.
