I had talked to hpindy earlier I believe had I only added timing up top instead of adding it throughout it would have hooked better I should have added it at wot only
I had it as much as 19.5 degrees of timing with no kr I gas octane set at 102-104 I did a 4th thru 6th pull in the hwy headed to the track and wow it was pulling hard and my logs show a very noticeable increase in torque
I can’t wait to see the 1//4 mile results

I bet you see it drop to 75 at times as well and even though your duty cycle is low when its dropping even to 75 psi your duty cycle will go up in turn ,it should stay at 79+ at wot if you log it you will see that the desired pressure is 80 at wot
Update - I did some logging in 50 degree air checking my tune. I did see the fuel pressure drop to 70 or so psi when aircharge was on up there and close to 6500 RPM shift point. Inj DC never went over 62%, Inj PW never went over 11, and lambda stayed at .82 - .83 so not something I'm concerned with but wanted to update with the observation. It seems a certain set of condition must be met for this to occur as other logs in identical conditions fuel pressure never dropped below 78 psi.
I've seen some Redeye logs recently and their fuel pressure was over 100 psi. Both of these are quite a bit more than my old R/T where 55 psi of fuel pressure was considered plenty.
ISNT YOUR FPDC SET TO 100% AFTER ALL THE ISSUES I HAD WITH MY PUMP IF MINE DROPPED TO 70 ID BE SUSPICIOUS BUT IT MAY BE NOTHING JUST KEEP AN EYE ON IT ,I LOVE MY JMS MY FUEL PRESSURE HAS ONLY BEEN AS LOW AS 88 PSI BUT CONSISTENTLY STAYS ABOVE 90 AND SINCE I CLEARED THE P025D FAULT FROM CAUSING THE CHECK ENG LIGHT IT STAYS 89 T0 AS HIGH AS 94PSI WHICH IN TURN HAS NETTED ME MORE POWER AND MY INJECTOR DUTY CYCLE IS LOWER AS WELL
Be careful with the timing. I'd try to have someone video a couple of runs for you and focus on watching the exhaust. We can't 100% trust the knock sensors in these cars. If you're not seeing any STKR, you need to double check by watching for puffs of smoke from the exhaust as you go down the track. If you see any, it's detonating. If not you're G2G.

I HAD A FRIEND BEHIND ME ON THE INTERSTATE WHEN I DID A 4TH -6TH PULL HE SAID HE SAW SOME GRAY LOOKING SMOKE WHEN I PUNCH IT AND THAT WAS IT BUT COULD SMELL THE RACE GAS IN IT
