15/15/15/ was nice cruising 22/25/15 isn't as much. tried lots of timing on the low end vs what I've normally been using and it was just smokier.
So I reset things and taking a a different approach. started with 19/19/19 and 28/28/26. I seriously don't think I'll gain much with HLD much over 26 at this time based on my rail gauge while under 3000rpm. That's holding 22K-ish
High heat, high humidity. For some crazy reason it's 90 degrees and about to rain humidly all evening.
It's smokier if I just get on it aggressively, say cruising at 15% throttle and go right to 50%, no rattling, no stumbling per sey, just a smoke show and go. Cleans up at WOT in 6th, 58psi-boost 58psi-drive (might turn the gate a full turn tighter). just a nice haze.
I still get this SOTP feeling that the truck pulls so much better over 3000rpm. I can't wait to get on the dyno to validate this. At the same time I'm thinking that I have a stock cam, why the heck is it pulling better with higher rpm? The power band should be lower right? Doesn't make sense.
My new approach is to start bumping up the LL numbers. I'll run 21/21/21 after the rain passes and the roads dry up. that might have to wait until tomorrow unfortunately so we'll see
As for the drive ability, I think I'm just getting used to things. running 19/19/19 wasn't bad, wasn't hard, could be driven smoke free, didn't "get away" from me. So there's defiantly a re-training a manual trans driver will have to go though
Anyone have suggestions for a direction in tuning for high heat, higher humidity days?
I think It's time to get a coolant bypass. so far I've been lucky...
