any datalogs? if you are getting any knock it will pull power. also the not making power on a custom tune is the fault of the person custom tuning it, i would find someone else, i recommend hemifever or stu at inertia motorsports. when i install a tune in mine it doesnt seem to take hold instantly. it resets the computer after the tune installs so it seems like it takes around 200 miles for the tune to settle in and mature. there are people on here that would say it takes hold instantly but in my experience it takes a little bit. when i first put my tune on it runs kind of bad, but after a couple hundred miles it really pulls.

Was this tuned with the handheld or the CMR software? If they used the handheld, this isn't a professional anything

he used software off of a computer. I fixed the high idel fault code by putting the factort programming back in.

Bad typing. I fixed the high idle fault code by putting the factory programming back in.

But I do want to add to this. Why did I lose horsepower and torque?

no way to tell without logs and an experienced person to view them and interpret them

The high Idle code was set due to the new TB. Because of the large blade it needs to be open less to keep the stock idle. When you put back the stock program is reset the adaptives.

The lost power is undoubtedly due to knock retard.

The loss of power was prior to putting on the larger throttle body. The loss of power was after the programming was installed w/Diablo’s programming. Yes, he did all the updates/patches. Yes he did from software.

I put the stock throttle body on yesterday, reset the codes, and 0507 kicked back on. Reset the codes again, it kicked back on. Reset the codes, put the factory programming back in today, it hasn’t kicked back on.

You guys are completely failing to understand is I went to someone who is highly recommended by Diablo, who is sponsored by Vortech, AEM, Baer brakes and others. This is the reason why I did not do it.

You are also failing to understand is he spoke with Diablo……….
