I normally shifted @ 5500 prior to cam & springs, & not over that.

I wanna do 5500 just to compare to before as close as I can. I know it'll be cooler tomorrow. Then ramp it up from there. You do know it was 15.0 before right?

 

Not sure, Ive never tried before. I know Ive ran my truck up to 6600 holding second messing around and thats a bit above my shift point and it was still holding. My fuel cutoff is set at 6800 so it probably wouldve let me run it up to that before it cut out, Ive just never actually set out to test it

Your tune is unlocked right? If so changing shift points is VERY easy to do.

 

5500 is even almost low for a stockish 5.3, spin that sucker up till you hear some clanking then back off a little..
and i thought it was 14.8 before? either way id hope you at least knock off .5 with a cam change..

 

I think my fuel cutoff is 6200 or 6300, when I viewed it a few days ago prior to my tune. I guess I'll bump that to 6500.

Yes, I'm unlocked. He never locked it from day 1. Even before I had HPT. He knows I don't want it locked, & also prefers me tweak tranny, as do I. I'll leave the engine tuning to someone else other than me. Til I learn a bunch more.

I forgot what trans table u tweak shift points from. Or is it pretty self-explanatory on HPT?
Sounds like before I go, do another tune w/. raised fuel cutoff & upped shift limits. Points I'll do another time. A shift point should only go up /down by what? 1-3 mph? I never changed any trans tables when I did trans & stall BTW.


skolman, it was 14.8 prior to FLT L7 & stall (no tonneau, jack, nor spare). I was told tonneau is 110#, spare is ~59#, jack is ~26, so I figure ~200#. So I figure that 200# = .2.
Next time after trans / stall, but w/. tonneau, jack, & spare, I ran 15.0. Took out the spare & jack, it did nothing for me. I also later removed tailgate, but the tonneau was still on for all 5 passes. How do u add a 2600 stall & not get any faster is beyond me.

 

The reason your hp and tq numbers seem so off is because you're only spinning it to 5000 rpms. HP and TQ cross at 5252 and you will make peak torque before this. Your HP numbers should climb just into 6000 with your setup. This is why your HP number seems really low and your TQ way high, you are only doing half a pull.

Btw..if you are worried on start up after filter/oil change, fill the oil filter with oil before you install it.

You are doing a good job, keep it up.

 

Matt, I knew 5252 is where they "X". I sure didn't know the hi-lighted part.

I normally fill filter w/. oil tho. I'm just like that.

I'm tryin, I'm tryin.

 

Didnt you go up in tire size between the 14.8 run and when you put the converter in?

 

No sir.

No tuning for stall or trans was done what-so-ever. Maybe that's how u guys get these .3-.5 gains w/. a stall. Or my stall isn't enuff over stock to make any difference.

 

Right.

 

I'm also thinkin the Radix will up that stall a bit, like when someone goes from a 5.3 to a 6L. Or whatever, as in more cubes.
