Interesting. First one is just the off the shelf 93oct tune from COBB? My best on that tune had a 0-60 of 4.911s, despite a slightly faster 60' of 2.029s. You were actually at a drag strip for that run? Wonder if I was slightly up hill.
The first pic is on the street with my own tweaked Cobb tune. With that same tune I ran quicker on the drag strip with a 13.3@102. The 60ft time on the strip was 1.99 sec. LOL The truck weighs 6k lbs, so it takes a serious torque load on the trans to get it moving.
The second pic is also on the same street with the E40 tune. I haven't had it to the strip yet. I also have a Draggy and will likely give it a go when I'm done with the tune. Based on my previous experience tuning the truck (and my other vehicles) and testing on the same "semi-private" section of road, I think it will break into the high 12s on the E40 tune. Well maybe...
More notes/info for anyone interested:
In my experimental/learning on tuning this particular engine, I've pushed it into some issues with airflow at ~71.6 lb/min that maxed out the MAP sensor @ 44psi (at my local baro of 14.7, yeah I'm at sea level) and hit 2.609 Actual Load. It made the engine VERY unhappy with me. It took 0.6 seconds for me to get off the throttle from when the event started @ 5800 rpm.
I've backed it down to run airflow right around 57-60 lb/min. The ethanol is a wonderful fuel for making big power. With the limits understood, I'm still advancing the timing with no knock events, except for the big audible event above, but it takes an awful lot of E40 for the engine to be happy with it.
LOL This is why the really serious-business aftermarket tuners (Note that I'm just an enthusiast self-tuner using the awesome tools developed by dedicated people like Trey Cobb and his great staff of developers) buy a vehicle of their own to develop their specific tunes for it. It really is a learned, knowledge-based undertaking worth every penny of the cost. Now, once all the basics are learned and stored, each new sale is relatively easy in that the limit parameters are set and the follow-up e-tuning is generally fine-tuning (no pun intended) for the customer's location and any specific preferences.
I REALLY respect a few of the business tuners like Winfield of GooseTuned and Adam of Tune Plus. I also like MPT tuning using the nGauge, but I never got to know them as I was just waiting for Cobb to release their products for the EB Raptor. I moved the nGauge to my RV to set up a tune for the 6.8 3valve v10. I did buy the HPTuners hardware and software, but I like the Cobb products better mainly because I've used it since ~2007. I'm sure there are more reputable tuners out there, but there are MANY hacks, so...
