Overlap greatly exacerbates the issue especially with a converter that is too tight and fully loads the engine too early.

yes it?s the same hummer, we had Nate kuhle build our base tune then he backed out, I think Derek said he was able to fix the fuel trims but I?m not...

So, kid went to bed early and this engine was on my mind, so i did some tests. Did the shop-vac to the intake method, absolutely no air leaks...

yeah i understood your reply, thanks. all i found so far is the gen 4 way of getting the ghost tune. but mine does not have the settings to adjust...

You're welcome I should have also mentioned that if you search "Ghost Cam" there are several videos with approaches people took. I had pops &...

I know this issue was a good while back now, did you ever figure out your issue? I?m having the same exact issue with my 13 CTS V. I?m running drop...

Thanks for the heads up, Whittlebeast. I was looking for alternatives, I will check that out. Im sending the mpvi3 back, hopefully they can find...

A lot of possibility's there. Is the cam timed properly during assembly? Did you replace the lifters? Have you done a full compression test? Quick...

Man if it works you are a true lifesaver. Where in the vcm editor do you disable it ?

thanks for the reply. i was waiting for the "why do you want a ghost tune" and i get it, just cant do a real cam just yet. so thanks for not being...

Thanks to those who read. I was able to borrow (test drive :secret:) a 2016 DCT and got a clean stock read. For anyone who needs a stock file to...

Just so you don't think I'm blowing smoke up your ass on this either... When we put the new racing long block in the car and started to go north of...

The 58 tooth reluctor wheel is spinning too fast so the pcm pics it up as a misfire. I disable them in the tune. Im running 26psi on my supercharger.

In the context of idle, it's part of the Adaptives.... Idle>>>>RPM>>>>Adaptive Idle>>>Speed Control>>>Immediate The Immediate table shows the...

You checked compression on every cylinder? Majority of the time backfiring in the intake is either a lean pop or a ignition issue.

This should get into power enrichment before boost enrichment. And your injector tables are not set up for a boost referenced fuel pressure...

I use TUTD for all driving. I will sometimes make a hit without revving to the upper rpm that it will auto shift for me. (Short shift) The screen...

its backfiring in the intake under load especially from a dig and absolute no power even at high rpm. No weird noise from the engine; good...

I vote trying another PCM and starting all over.

So probably needs a rewrite with TDS/SPS or another ECM rewritten to stock?

Hi, im chris. new to HP Tuners but looking forward to playing around with it. i have a 2018 camaro 6.2l and a few other toys, looking forward to...

Thank you for the insight! I bought a smoke machine, should be here in a couple days. I looked over everything again and nothing is obvious to the...
