Ok so about two months ago I purchased my 05 lly 2wd 210000miles I did the PCV, resinAtor, cut the air box, etc then added a edge cts evolution. After a few days on level 4(extreme) it started to get really bad (what I assume to be) "clutch shutter" when under load in 3-5gears so I lowered the tune to economy and started being nice since I can't afford a trans!!!!!
A week later someone GAVE me an egr block off plate so I threw it in and the truck is only throwing soft codes about the egr air flow etc. in this time I had towed/drove the truck like normal! Even towed my full size k5blazer all over the southern part of the state of az and I had no issues/shuttering
then about two weeks after that I got a wild hair and decided to throw the tuner on level 3 to see if it would still shutter! Well to my suprise the truck ran great!
So then tonight I realized that I still had not done any "update" on my cts and it was "recommended" to do so before installation! So after updating I put the truck on level 4 again and test drove the truck and again NO SHUTTERING! Even when I pulled a hill in 5th gear with torque converter locked and 25lbs of boost!
So my questions are
1. Was I actually feeling trans slip/clutch shutters!
2. Was the egr maybe causing some kind of quick airflow issue that was causing what I thought to be shuttering?
3. Would the new update possibly bump up my trans line pressure and that's why it quit (for now) "shuttering"?
4. Should I be worried? Hahaha
