Mine taps/makes noise mainly at 1300-1500rpm low shifts, right before the shift. Somebody told me it was from my tq management and the ecu is pulling timing before the shift. Is this true?

I put the 10w 40 Castrol in it yesterday and it did quiet it down a bit. Can still hear it but not near as pronounced.

 

Mine's pretty loud at 1500 with light throttle, shift or not. Sounds like a Cummins diesel almost.

 

hahaha mine is more like duramax level not cummins. Good to know though!

 

I had sent the clip to brian tooley as well and he just got back to me, said the comp XE-R lobes that texas speed uses are known for being noisey followed up with "thats why I dont use them"

 

That is a true fact, but from what you were detailing it sounds pretty normal.
