Here is the deal with the flat spots in acceleration.

1. It should downshift, because these trucks are dogs in high gear at 2K RPM

2. Are you talking about going up a hill? Because these trucks poop out going up a hill in 3-OD gears. At 2K RPM, they will just slow to a crawl up a hill.

SCT will help that. Also, use that spectre drop in. I know you are worried about fine dust, but if you are willing to change the oil every 3 months OR 3K miles, it will not be a problem. THat is the rub with using the HPr filters. Keep the motor clean. So if you are letting more in, you need to change the oil more frequently.

ALso, did you put a 180* stat in your truck with the plenum fix? Hemifever recommends (and programs) his tunes for 180*.

Not a bad job. You can drain your coolant, change the stat, run a flush treatment and put in new coolant to "winter specs." Not a bad way to spend a morning on the weekend.

 

heads up on spectre drop be sure to take the name off of it, there was a thread awhile back about how the spectre chrome label came off and was sit on top of this guys TB

there are 2 sensors 1 is the temp gauge sender and the other is coolant temp sensor for ecu .the sensor will have the 2 wire plug the sender is a single wire both are on the front near the tstat.

 

Lol, yeah that was me! One of the reasons I took it off.

 

Yes, is 180 t-stat. Oil changed every 3k already...but if the cloth filters let more dust in, well, that aint good no matter how often you change the oil. I don't know if they let in more or not, but probably.
