Lol... come on Clap. Some of the comparative results posted on Cobb's database are questionable at best. I recall there being two cars racing each other on video showing very different results than what were shown on the dyno.

Look it up yourself, the customer was there with the print out. You think they would publically lie and potentially be caught by the owner?

Finally! Now I'm just waiting for some trap speeds and I may just jump ship to a Cobb.

Oct 4th ill be at the track if the weather permits.
Stage 1 went 112 on my car.
People on here have went as high as 114 on stage 1.

Stage 2 on my car will go 114-115 based on the butt dyno, some will go faster, esp the auto guys.

Like usual ill post the results.

Oh you mean the 335xi manual vs the auto 335i jb4 car? yea cause that was fair lol
Do you recall the owner of the xi car saying how he got smoked when he owned a jb4?

Mustang dynos are fudged they all read different ..the Cobb dyno reads high for a mustang ..I want to see the Cobb Fbo on a real dynojet(not virtual dyno).

Ok one last question. Procede vs cobb, is one more "friendly" to AT than the other?

I don't recall seeing many independent dyno results from Cobb users. Perhaps they just aren't dyno testing their car. Or perhaps they are and just aren't posting results. Hopefully this trend changes in the near future now that Stg2 is released.

Both are nice to your transmission. 6AT issues only start to be an issue at much higher power levels (upgraded turbos running 18+psi of boost).

cobbs mustang reads high? They hit 240whp stock. When i was bone stock I hit 242 whp on CP-E dyno. With a dci/charge pipe 40k miles later i hit 251whp.

As far as numbers being fudged with, why would cobb post up all these results, its only a matter of time before people starting hitting personal dyno days. If numbers dont match up, they just burned them selves. Only an idiot would do something like that.

Looking forward to it. Trapping 114-115 on pump gas with no meth is impressive.

If you think the COBB dyno reads high, you are just plain wrong. I have been to the Austin facility and that dyno is a heartbreaker.

My buddy barely made 330 or so whp on it and 370 wtq or so. And his car pulls very very hard. Harder than mine if I dare say it. His trap speeds are all much higher than mine, even if our E/T's are the same.

This is not to add to any tuner wars, but rather to point out that COBB's dyno does not read high.

From Cobb:
Stock Vs Procede (no mods)

67 Delta

Stock Vs Cobb Stage 1 (no mods)

73 Delta

Stock Vs Giac Stage 1 (no mods)

71 Delta


We can see the majority are in the same ball park on stage 1 and stock. So looking at peak numbers there is no differnece, atleast not on stage 1. You also need to look at the power under the curve and realize there might be some underyling factors here like heat soak.

Also the dynos definitely do not read high. With baselines of 240 they are on the low side. Realistically you can put this car to dyno 270-280WHP stock.

Let's just say it is!! My buddy made 600 on their dyno ,then 620 on a dynojet !! So it reads high..a real low reading dyno reads 16% lower then a dynojet!

I understand cobb can monitor each cylinder's ignition advance, but can they adjust the timing for each cylinder as well? Because that is huge compared to piggies which from what it seems can only monitor one cylinder, and can make a big difference in consistency.

Did you see my post? 3 cars just dyno'd 240WHP stock as baselines when the car normally dyno's 270-280WHP stock. It's hard to claim that EVERY dynojet reads 16% lower. Conditions might have changed for your buddy where he should have made more on the dynojet. Comparing dyno to dyno and car to car is pretty moot, just compare delta and power under the curve. However realize their are other external factors that can aid or not benefit a dyno run. (heat soak, octane, adaptation, miles, sparkplugs, boost leaks, ETC ETC).

When every other tuner's dyno on stage 1 makes 340-350WHP they only made 310-315WHP on Cobb's dyno.

Nice, i just didnt feel like doing that. There a jb4 and dinan dyno in there as well.

Based on those 3 the power under the curve goes to cobb so far. Looks like that boost down low with proper timing works after all.

I have been there in person and can guarantee it does not read higher than it should. Don't accuse COBB of fudging the numbers when the runs can be verified by members on here who have actually seen the cars on the dynos and can back up what they are claiming.

And perhaps the dynojet read low? Who knows?

If COBB's dyno reads high then you are claming that a car making barely more than stock power is trapping approximately 113 in the quarter?

No, there is a set curve across all cylinders, and the DME (as it does stock and on piggybacks) makes cylinder to cylinder corrections. Ideally, you want no dropouts, but that's a tough task, even for the stock tune.

There are a couple Jb4 but I think something is not right as the deltas were 40WHP from stock to map 1. If they are in fact right someone else can post them. I dont want to be shot at for being the messenger of poor dynos LOL

[Clap135]

People need to stop referring to cobb like they do to piggy backs. It is a stock ecu that is reflashed to run different parameters. It still works on the stock ecu logic just like a stock car, but faster.

A piggy back tells the ecu its running stock and alters certain parameters to its best ability while the ecu doesnt see any of it.

Well I think most of them were map 1 and autotuning which ended up being the same as map 1 or lower lol.

I think dinan stage 1 came in at a little over 300 as well.

Regardless of what kind of tune you use, the DME monitors and adjust individual cylinder ignition timing. With piggies, you cant currently see this happening because you can only see one cylinder 1 advance. But it's still happening.
