You should trap 110-112 with a decent launch.

If you are basing a tune based on solely trap speeds then you should reconsider tuning to begin with.

Don't assume, thanks.

Obviously my post was sparked by the poster that posted his 108 MPH trap w/his Cobb tune. If you go back & read the chain of my posts after & comprehend things, it'll fall into place. I never said this was the only item I cared about. Have a nice day.

It's probably suppressing the ses light but the o2 sensors are not ready. Just like that auto code clearing feature on the piggys

Go to the track run the stock map then throw on your jb plus then throw on Cobb stage 1. Log all 3 and it should be clear as day. Also comparing your result to one Guy from a different location and car to yours is pretty useless. I've seen bone stock cars hit 105-107. does that mean your jb lost power at 75 percent?

If it helps you, the AP said I went 0 to 60 in 4.2 seconds.

If you trapped 113 you have more than just a tune. The only other mod I have is BMS DCI. I won't be trapping 113.
There are many factors that contribute to any given ET/trap speed. That 113 trap speed I got was in 95 degree weather. Yes I am FBO. I haven't always been FBO, yet I still got great value and benefit, even when I had fewer mods.

If it was colder, maybe my trap speed from last week could of been higher at 115 mph. I have used both the Procede and Cobb AP on my vehicle as well as been dyno'd with both tunes. The power increase is substantial (I trapped 109 with my V5 in cooler weather with just a tune).

If its too expensive then sell it, but the features and control that the AP has over various engine parameters are in a different league than the JB+.

The piggies (V5, JB4) and the AP (being at the top of the list) is the way to go.

I've trapped 115 with a jb3 dci and dps only before. Doesn't mean a thing if you don't know the DA and track conditions.

Of course cars run faster in cooler weather.

I think you guys are misinterpreting my post. I never said there was no benefit of Cobb vs JB+.

Never said it was too expensive or the control/features are not better. All I said was an extra $700 for 3 MPH is not worth it to me.

With that said, stop assuming and I do think I will see more than 3 MPH gain when I head back to the track. I am expecting at least a 12.7 out of the car & I would be happy.

Has anyone integrated meth with Cobb yet? If so, how does it work?

Works fine....just like Meth on the stock tune. There's nothing outside of a failsafe to intergeate. The e u does all the work instantly.

You can run methanol on any tune. The difference is the piggybacks integrate with flow controllers/failsafe and switch between high and low boost maps depending on flow. Naturally, the Procede PWM kit goes above and beyond as it maps the right amount of flow based on several factors.

You can still run methanol on a Cobb tune but you need to have all your ducks in order with a proper fail safe and 3rd party controls. Naturally, on stage 1 its quite useless as the benefit of methanol is only found when turning up the boost and adding ignition.

There's zero proof that any of the so-called "failsafes" actually save the engine from failure...they're just there to lower boost and/or introduce some timing retard in case of meth flow failure but this has never really made running meth on high boost any safer...on the other hand, having it doesn't hurt but i really think it leans more towards a false sense of true "safety" that towards true engine safety...

Its great that it allows a tune to run lower boost when there's no meth flow BUT if that meth is being used for octane enhancement (as its the case in many setups here especially on questionable pump 91 gas) and meth flow stops at high boost high RPMs, there is no proof today that any so called failsafe "prevents" sudden motor failure

Your 3 mph metric of the tunes benefit is VARIABLE.

Beating a dead horse here.

Sounds like your just arguing for arguments sake.
Your opinions on the matter are quite moot. Failsafes are designed to let you know there is a problem. Whether they are 100% bullet proof is up for discussion (and one I find quite pointless) but at the end of the day it is better then running blind.
