You can look at TPS as well as RPM.. at cruise both should be relatively steady..
What is the end game of figuring out you're at cruise?

Well I got some 7 x .012's in the truck, up from my 7 x .009's.  Didn't have to change anything in the code.  Props to hakcenter for the RPM logic it works well.

Good job!  I would guess these are VCO injectors?

What dash? 


7 x .012's vcos set at 330 bar rather than 310 bar.  Using my Quadzilla tuner to pull duration down to 68% of stock at 0psi and walk up from there.  small timing adjustments in the tune as well, but not near as much as I thought.

If I do new injectors at some point i'll probably go to VCO's.. the SAC's I have are just too dirty..

Have to agree, sure the SAC's flow more but they just seem too dirty

OEM choose them for a reason.  I have MORE than enough power now, Gaining 15 hp with SAC's I could care less about. 

More videos.  this one is a passing situtation, or at least emulation

Took it to 30 mph, in 3rd, locked the TC and did a pull to show lugging the motor transitioning into boost coming up and passing.

Looks like the VCO nozzles may be getting fast tracked.. see my thread for info

Well I moved my 65000 rpm to 105000 vane position up by ~1 cm.   this has solved my barking issue and keeps my DP from going north of 50 psi on top.  I am pretty dang happy right now.

DP to B ratio is 1.42 on my "race curve"
