Ya probably a factory error, and it happened on the stock tune! I had just switched back from my GearHead Tune to get a stock baseline on my dradgy. Which is actually good because now I can’t blame the tune for it haha

First thanks for the compliment. That morning I drove all of 3 miles to church and squeezed one 0-60 run in. Then sat there an hour, drove another couple miles to the car wash, then jumped on the freeway for 5 minutes or so. Pulled over and did a 1/4 mile pull. Got up to 107 and the damn sport...

So I had a scare the other day, the engine abruptly overheated and the dash started yelling at me after completing a 1/4 mile run. Upon pulling over I noticed the signature coolant smell and coolant on the freshly washed car. I popped the hood and saw what looked to have been a coolant...

Curious if you have anymore feedback on this. Have you had a chance to try anymore dradgy runs? How does the e30 compare to the A/O?

Got it - thank you sir!

What do most of these tunes (JDM, PBD, ZFG, GearHead) hit on 93 octane?

Gear does not display. I have only heard of ZFG having the ability of doing that

So not to argue because I know you know your stuff. But per GearHead they told me via email that they allow up to E20 on their AutoOctane Tune. For a higher ethanol percentage they offer a specific E30 tune which they highly highly recommend only using if you plan on upgrading the intercooler...

I’m would love to hear your opinion on that E30 tune once you get it up and running. I have been thinking of getting it myself, but a little hesitant based on @ridered74 testimony

The E30 tune gave you same numbers as the A/O?? That seems crazy seeing their dyno. Something isn’t adding up

So how does the GH E30 Tune compare to the JDM Tune? Both claim high HP numbers

That’s not mine. I took it at face value. Mods are listed as tune and upgraded intercooler. I took it directly off of GearHead’s website. Not my personal data.

I looked into the JDM Tune at first but it was a little more pricey and it sounded almost too good to be true to hit those types of numbers on a caned tune on 93 octane. Those are ZFG numbers! The JDM Tune claims 100+ HP & 150+ Torque.... Based on the dyne that GearHead posted this is what I...

Also using the GH A/O tune here in So Flo and loving it. The sequential transmission shifts and elimination of the Sport Mode gear hold was worth the cost of the tune alone. The added power is the cherry on top and I think the truck now drives as it should have from the factory. Even the Sport...

HP Tuners MPVI3 (w/ 0 credits) Willing to trade or sell. Asking $150 + shipping if desired. Located in Florida.

If I did my math right, that’s basically 3 gallons of e85 added in a full tank of 93, correct?

Oh! Right on! Ok so I’ll keep the mixture closer to e20 then. If I understand you correctly - having more than e20 won’t hurt, but it also won’t really help with this SPECIFIC Gearhead AO Tune.

What is the main reason people typically don’t do things? PRICE. I have a family and can’t justify spending that, regardless of the benefit. The Gearhead tune was relatively cheap and came with an instant benefit in performance and transmission function. I was a huge hater of the 10 speed...

Impressive bro! Couple questions: Gearhead recalibrates the tune once an intercooler is installed correct? Did you have them also recalibrate it for a higher ethanol percentage? Also how did you come up with the e24 mixture rather than full blown e30? Is there a specific reason or benefit...

Damnnnn! The intercooler is definitely a weak spot! Kind of a stupid follow up question, but theoretically a tuned heat soaked engine would still outperform an untuned heat soaked engine right? Or is the heat soak so severe that it limits the performance to a “safe zone” regulated by the ecu?
