    TVS Coyote F150 laying over above 6200rpm

    Looking for some suggestions, have a built 16 F150 coyote, cams, forged bottom, 2650tvs, twin69mm tb, return fuel, that seems to pull like mad all the way to 6200rpm, 640whp, then falls off, here's my file and the last dyno run, looking at the scanner log I'm not seeing the throttle close or timing pull above 5000rpm all the way to 7k, I did see a couple degrees of timing pull from 3500-4800rpm I need to address, we feel this thing should't stop pulling until a bazillion rpm, we'd love to see 700whp@7000rpm, have a look any advice is appreciated, thanks Brett

    my 2 cents is through your whole pull you never get into optimum performance. you stay in best fuel economy. your cam angles in best fuel economy might be why its falling on its face. also you should have your weighted vct mapped points logged(each mapped point), 14-25

    I should also add this file is originally a dealer installed Roush TVS kit, and I just noticed that while road testing that map14 stays 100%. I realize that many think it a hack to lock one map, right now I have great drivability, no codes and such. Am I opening up a can of worms turning the system back on? Thanks again

    I would compare with some other F150 TVS tunes and do some trial and error on what you want/like.

    This is the first F150 TVS we have done, and there doesn't seem to be a lot of files out there to compare ours too that aren't originally Roush tunes.

    When you log VCT schedule mode it will will tell you what mode your cams are in, best fuel, fuel,economy, OP etc

    Spending time aquatinting myself with the software and forgot about the tabs on the left side for the channels. One thing i wish we could do is build and save channels without being in the car. Since we can pull the calibration off the car one would think that making channels offline wouldnt be that difficult but im just a laymen so what do i know lol

    You can build a template and save it.

    You have a lot of throttle angle error. I picked up 27whp on my Whipple Coyote by reducing my TAE to near zero.

    So I have the map points working now, definitely a giant improvement everywhere. My issue now is that VCT Schedule Mode is going from working properly to disabled, sometimes right from key on, and consistently after driving and releasing the throttle. I suspect it has to do with the throttle setting or the VCT Map Points or Distance table settings, as always any help is greatly appreciated.

    Why do you have 6.00 lb/min unmetered airflow leakage entered into value [ECM] 35184?
