Lund Tune N/A Worth it?

[Jordan @ Lethal]

What happens if you use E85 without a TUNE, just stock 2019 GT?

Don't do that. E85 is much higher octane and requires roughly 20% more to get the same combustion as gasoline. Calibration is required.

I started off with a Pump Gas Lund Tune. I did have long tube headers prior to the tune.

Had my car in for some body work, and my panel man asked "what have you done to this car? Its so much faster than my dad's" (same year model).

Then I moved to an 18 mani, 47lbs Ford racing injectors and E85.

The thing seriously flys! Havent yet had her on a dyno, but just from real world... the Lund Tune has been great.

Wonder if anyone has done the burbles option with their tune. I miss that from my F-Pace.

Don’t do it. Lund doesn’t recommend it. It serves no purpose and is only good for blowing out your mufflers.

I would find a local tuner who has a dyno and doesn't do cookie cutter tunes.

This.

 

[WildHorse]

Yep worth it. CAI not so much. Should pick about 20-25whp tune only

Normally I agree with the things you says, but the PMAS is a killer setup on a coyote. My former JLT did next to nothing mind you haha.

Supposedly pmas is as good as it gets for NA set ups? I gained 7 peak hp with a airaid cai on the 15gt. So there were dyno proven gains. But If I had to do over again. I don’t know if I’d spend $350 for 7 peak hp. What were your dyno #s for the pmas?

What were your dyno #s for the pmas?

No dyno. but drag strip. Same test n tune day

Diablo_A_93_Stock-Maf ~ 12.18 sec
Diablo_A_93_JLT-Maf ~ 12.15 sec
Diablo_A_93_Pmas-Maf ~ 11.91 sec

all runs 60'd in the 1.7 range +/- a few hundredths. All those tunes were the same except for the MAF size & fueling trims obviously.

Nice, what were the trap speeds? Who's your tuner?

Running upgraded half shafts with your setup WildHorse?

First two 118 and change, third was 119.5 iirc.

No Sir. If it ain't broke don't fix it. Also, thank you bias plies haha.

I've got a Lund Flex and E85 tune. I have a 2019 PP1 convertible with 6 speed. My good friend has a 2018 PP1 6 speed convertible. We've driven lots of places and done some races against each other. Here's the facts:

With my Flex tune and running 93 octane, we are nose to nose in almost every race. If someone is slightly ahead it's due to a quicker jump from the rolling start. We've rolled on in second and third gear and there's virtually no difference.

Now, switch to the E85 tune and I win every time. It advances my timing to 30 degrees and you can tell there's 30+ more HP.

I also added 4.09 gears. I love them and it makes the car fun to drive. We did some roll on's in second gear while on Flex tune and guess what? We were nose to nose. He's got the stock 3.73 gears.

I should beat him in some roll on's depending on the rpm we started at. He chose the powerband for his gearing. If we had started at lower rpms he would be farther away from his power band and I would be closer and get a slight advantage.

These are just my real world experiences. Some may disagree and that's fine.

I am the friend here and yes, my friends 19, running the Lund flex tune on 93 premium nets nothing over my stock tune. Both cars have drop in K&N filters in stock air box for what that is worth. He does have the 4.09’s that feel really good but wheel HP has not changed. One plus with the Lund flex tune is that the rev limiter has been raised to 7800 which makes the car easier to drive as you are not running into the stock limiter at around 7300. Running the e85 tune definitely wakes the car up as he can just pull away from me. What gains can be had running 93 premium, with long tubes headers and appropriate tune?

Well now that should ruffle a few feathers at the lund camp. And something for Yolo's monolog on tuesday haha.

How many 1/4 mile hits have you made on the stock half shafts? Slipping the clutch I presume?

I guess my question is why run a flex but Guage the performance on 93? Flex is for convenience but Guage it on actual e instead of 93.
