Hey man you put out a lot of great videos a lot of good information. You did mention one of your videos you going to start 5th gen stuff. I'm looking at my tune following your video some of the tables are different from this video do you have a video for 5th gen for this?

[@jeromeirving4770]

Hey Matt, have you ever come across doing a very limited dod delete(left cam in because it was still good and customer didn't have the extra money for a new cam). The tune at idle even though dod is turned off. It will still have idle and off idle trying to trigger the dod as a miss fire. It has a non dod gm valley plate. Thanks in advance

How would some of these settings change with additional mods? Ive done truck norris cam with ported heads, headers and full exhaust.

[@Matt_Sanford]

That information will come in other videos, little bits at a time.

I did a truck Norris and wanna know how to tune this myself. Been learning Thanks might need the GEN IV truck Norris cam in depth and more details. Do I know these numbers? What about 6l80 tuning? So many questions. Is your email available

[@Treyolwell_]

Do you feel 19-20 g/ps is a lot for a big cam 6.2 for the start up airflow?

[@A2RACIN]

Did this and its fine but when im on the highway and throw it in neutral itll rev up to 2k rpms.. why is that?

[@Chocoo813]

did u found out what it was?

[@A2RACIN]

@Chocoo813 i kinda did but its tune related. My tuner told me what part it was but i forget the name of it. Basically hanging idle if i recall

[@Chocoo813]

@@A2RACIN oh ok how long you was driving with this basic tune before getting tune right?

[@A2RACIN]

@@Chocoo813 its still not right but its ok til i hit the dyno. Using the stock tune with a few tables changed to idle and drive.

[@Chocoo813]

@ what year is your GM and did you have to buy credit points to do this for the first time?

[@modders_garage]

I have an 07.5 silverado i dont have 7000hz it stops at 5800hz

[@Matt_Sanford]

Your 7000hz table is in the High Frequency vs MAF table. 2007 has a Low table and High table. It works the same as what I have shown though.

[@modders_garage]

@@Matt_Sanfordwould i need to make an adjustment on my airflow vs freq low?

[@Pvtjoker122]

@@modders_garage Yes, you adjust both.
