lund tune w/o mods worth it?

[Idaho2018GTPremium]

I'll add to that. The E85 tune is just a different animal entirely but the tune overall changed my car up. Though I have a base car so that may be more substantial than those who have upgraded cars.


I don't drag race so I wasn't logging 0-60 times and what not but I can say there were changes in how the car handles on the base 91-93 tune. A10 shifts are much better. The car mechanically works better now. So from an experience perspective, it is a better car. Power wise, I'm going to safely say it isn't going to be a huge change. Though don't take my word for it... from the man himself

So, tune only (non E85) is worth 11.5 rwhp (430 rwhp vs 441.5 rwhp w/ stock air intake) on an '18+. Not that much, really, by itself.

The E85 tune picked up another 13.5 rhwp on top of the 93 tune (450.5 w/ 93 tune and JLT vs 464 w/ E85 tune and JLT). So, E85 is worth about 25 rwhp on a mostly stock car, considering the JLT intake was responsible for about 9 rwhp.

But back to the baseline dyno: 430 rhwp on a stock Gen 3 Coyote. Even assuming only 10% drivetrain loss that's 478 crank hp. I think 11% is more realistic, which equates to 483 crank hp (430 / 0.89 = 483). That's plain awesome.

Not really the same thing. I asked for before and afters of the same car same driver with DA data. You're comparing different cars and different drivers and tuned on E85. I was referring to a 93 octane tune.

My car and my buddies car are identical down to the color and options. Only difference was he had 1/8 tank of fuel and mine had 3/4 tank. lol.

Pump tune in manual or drag mode car is minimal power gains. You can still add in more timing in low-mid range which is useable on the street. We have already covered that in general. Pump tune in an a10 car without drag mode would still be worth it to add drag mode back into equation. So your blanket statement about tunes does not exactly pan out in auto 18 plus cars in 300a setups.

We done here...?

That is one dyno example. Pull in a hundred then do an average. lol

Under the curve E85 gains via timing is also worth more than just a peak number...

Keeping OEM cai on 18+ (smoother maf curve for flex tuning and cooler iats) and running flex/ e85 tune is worth more like 40whp generally, at least in personal experience and other observations. Best bang for the buck really imo. Plus can work even more in your favor if you add long tubes then CF DS and light weight wheels for less parasitic hp loss.

Plus in my experience the total tuning net gain is in direct relation to how many logs are you willing to run (on road, fuel you use) to make it as best as it can be for your particular car. A one log and done car is probably not fully optimized imo...

There is a reason Beefcakes cars are flash whores besides just the net parts changes. ;).

Agreed. Without logging and a little effort put into it its basically a canned tune. You get out of it what you put in.

Who you going to put your money on...?

Street race from 45 mph roll to take traction out of equation for most part. Two brand new 2020 GT’s with same options premium A10’s w/ drag mode. Both drivers weight about the same and both have 1/2 tank 93 fuel same station.

Car #1 has Idaho Potato driving stock tune
Car #2 has Lund tuned 93 with a few logs

Best 4 out of 5 to keep the lucky automatic driver honest. ;).

I hope some of you guys know the Lund doesn't have a seperate 91 or 93 tune. It's all lumped into a single 91/93 tune.

Don't get caught up with the dyno numbers for a e85 tune. Way more benefit than just the numbers. Power ramps quicker, better cooling,etc on top of the numbers.

For you data guys- Timing ramps and comes on way sooner.
For you seat of the pants guys- Yes, you can feel it and more than any other bolt on besides boost.
For you ricers- Feels like vtech yo!! lol

It really is noticeable, even on my 15 car. The flex tune performs well, but the E85 tune is a different feeling entirely. It spins tires off the line with much less provocation, which is an indication of more low end torque and throttle response.

I don't get into the empirical numbers too much. I care more about how it feels and performs subjectively. Just one man's opinion but this is one of the mods you can actually feel.
