Vvt help Alright a little back story. I bought a used Yukon Denali got it home. The vehicle had multiple codes for the vvt so I decided to just replace all of it.. that's when I noticed someone swapped the l92 for an lmg ... Man talk about a sh*t show from there. Well I'm stuck with this truck.
Here is the issue. I did a dod delete new lifters head gasket vvt actuator vvt solenoid new tensioner the works. I also swapped to a vvt non dod l96 cam all from BTR. engine was timed rolled over twice and verified to be correct again before putting it back together. Well now it idles fine revs perfect and dosent make any noises .... Untill I command 25 degrees of phasing with the scan tool. It did this while driving and the noise it made was horrible.... Come to find out there are two different cam pahsers one is 52 degrees of phasing and one is 62 degrees of phasing (total) and guess what one I installed... Well it's the wrong one ...
So what is the risk of just using hptuners and "deleting" vvt in the tune
And second can the vvt be tuned to not go over 20 degrees personally I'm ok with just tuning it out as long as there arent any problems doing that.

If I recall correctly, there is a difference in what a degree in the tune means in crank angle from the two different actuators. You'll be tuning it at your own risk especially getting into higher numbers in the vvt table. There is an older thread on HP tuners forum that dives into the differences.
