Few seasons ago I went a best of 11.96 on my 650 rwhp tune. After some eye issues that kept me from racing I went back out two weeks ago trying the spicy tuna tune for the first time. For a 100rwhp gain, I should've netted more than a tenth. Before I go out beating the breaks off this thing trying to log/identify it I have some ideas. My gut says fuel issue, I've launched hard enough with being non sumped, the truck has nosed over on itself on launch which leads me to believe starvation. I had 3 clean passes without breaking up, the others netted in sputtering between 2800-3200 in 5th. I was running a velocity stack too that night so I'm unsure if turbulence there could've caused that. Tune 4 didn't have this issue at all. I'm 65 overs with 2xcp3 so shortage shouldn't be an issue. Is it possible I need to sump it? Or any other restrictive areas in our fuel systems to look out for? I'm unsure what the factory draw straw will take. I know my charger is "rated" for a max of 750/800, and 42psi. One time I lost a map sensor racing and made 50 psi with the same weird break up, went new delco fixed the issue, then realized I also was collapsing the filter, hence the stack. This last time out I was making 48 psi which led made me wonder if it's either a maf or map related issue again.
Any help would be appreciated, definitely think this truck has 11.60s in it on SBE, maybe more if I get the boat anchors off all 4 corners
