GT 13.1 What's wrong?

[beefcake]

way tooo much going on.

i told you this in the messages, for them to say there is an issue with a tune is simply ridiculous, and these guys are incompetent.

lund ran in their n/a car this weekend i believe the quickest auto pass to date out of an n/a car.

we ran the quickest pass period in a car.

The results speak for themselves. You should have loaded the lund tune and ran it at the track.

Whoever your dealing with is incompetent imo and sucking $ out of you.

You don't need to keep going to dynos go to the track and run the car....

You already had a great tune that was custom done for you.

Honestly, any kind of dyno tuning should mop the floor with a remote tune. Especially if it is just a normal canned tune. If you are locked into Lund, I would just give John a call and see what he can do for you. He is a great guy, and will help you with whatever you need.

i am going to kindly disagree, as we proved this weekend, yet again

Forgot we already did this. It's in another post but real quick.

CB Baseline - 335, 329
CB, JLT, Lund - 345, 329
CB, JLT, Custom Tune - 351, 357

These numbers and all your experiences and problems are not normal. Your overall issue unfortunately could be a lil driver error (which is always gonna play a part) but possible motor/powertrain strength?!

My absolute stock dyno pull I put down 366rwhp and 345lb-ft torque...

your numbers are way too low in general but especially with upgrades.

And lastly... I just installed ARH Full system 1& 7/8' Long Tubes all the way back and uploaded a tune from Lund through Beefcake... and there is no denying they know what they are doing... my car hasn't even data-logged yet to get a non-canned tune... and the thing feels like a MONSTER!

Lund knows what they are doing.. plain and simple... which leads me to believe you have a bigger issue on hand (strength of car itself).

My advice... get it figured out with Lund.. stop messing around locally and with so many variables.

Hope all turns out best as possible and I am wrong. Cheers

Your 60ft is what's killing u. R u running with traction control and advance track off?

I understand there is a lot of parameters going on and partly my fault for not getting baselines in stages but a couple things are straight forward. I did re-word/correct the statement that all they said is it was leaving power on the table, not that it was wrong.

Beefcake please see:

Are you saying they are purposely making these numbers in their favor?

DRKHR5 - were those numbers on a Mustang dyno or DynotJet ?

I will also be going to the track Friday.

You can't really compare dyno numbers like that (even though we all do). But you really can't take his Mustang dyno numbers and compare them to your dynojet (I assume) numbers. Not even close to an apples to apples comparison.

Your 60ft is what's killing u. R u running with traction control and advance track off?

His 60ft time isn't really going to affect his trap speed. Which didn't change at all with the tune. That doesn't seem right.

Given he only picked up 10hp and 0 tq with the lund tune, I wonder if somehow it didn't load properly? Though don't see how that could happen and still give you a drivable car. Or maybe the dyno operator messed something up somehow.

I think bottom line is, OP need to find a way to get some datalogs and let lund take a look. And, like beefcake says, try run the lund tune down the 1/4 and see what happens to the trap speed.

Try the Lund tune on Friday.

I would hope they are not purposely fudging numbers. But bottom line is the Lund number looks off - for whatever the reason may be.

 

[Mark5825]

My best guess would be they just didn't care much and didn't really try to get the best numbers with the Lund because the numbers looked odd to begin with. Just gotta get some more actual times until this can really make any progress. At worst the Lund could just need to be adjusted, but every shop (even ones that don't tune) has said a custom tune is better simply because every car is slightly different and will need minor adjustments.

And this is why you data log and send them to Lund - so they can fine tune. But I get it is tough for you to find a road to do this. You could do it on a dyno as well,but then, obviously, you have to pay for dyno time and it may take a few iterations to get everything nailed down - so could add up quick.

Just run both tunes at the track on Friday and see where you net out.

What a simple answer lol, and yes I will.

 

[beefcake]

in reality, I could car much less about dyno numbers, unless... you are doing a back to back direct test, datalogged, multiple pulls over and over.

load the lund tune and go drive the car.. see how it feels, you already said it feels better I think.

just throwing $$ away imo

Livernois Motorsports - Kooks was what I was thinking before I asked them. Do you have tests on a Mustang dyno?

They make a top notch product, solid vendor!

No we actually use 2 professionally calibrated DyonJet dynos. One AWD and a portable 2WD.

 

[foghat]

What a simple answer lol, and yes I will.

I suppose, ideally you get to make a couple passes with one tune, then switch and make a couple with the other.

Solid advice!


If you still can't get it ironed out, give us a call!

Dyno Jet.. Phoenix AZ 95 degree dry day. Ill try and post my graph when I obtain it myself... (no pc to download it!)
