here is the bad passes

i only thing i noticed, the first 2 "good" passes had no burnout
3rd pass had burnout and bogged

either dont burnout or burnout and raise launch rpm

 

Sounds like my car when I ran a couple weeks ago for the first time with the car on slicks. I had to up the boost and launch control in 1-2 gear and then it stopped bogging.

How long did the E85 sit in the tank and what fuel pump are you running ?

 

see thats the thing at the same psi in first and rev limit on launch with thrid gear burnouts it never bogged it would actually spin too much we didnt make any changes im thinking something electrical is wrong or a miss fire i think i may be running 3 cylinders when it does this some things loose or connection idk but with the same settings the car was running fine and lauching no bogging nothing

 

the e85 i drianed it sat for a month and a half but i was letting the car idle a few times a week then drianed it and added new fuel days before i went to the track fuel pumps are a walbro intank 255 and a inline 044 i was thinking maybe a pump went bad but afr on the data logs show dirt rich 10.2-10.98 so i x that out i know when i checked the plugs today plug 1 looked almost closed there gapped to i beleve 15 or 13 im gonna check in the morning

 

also listen to the motor it sounds completly different when i say its running bad sounds like a subaru or all motor theres no power gottta be a cylinder not running

 

What style injectors/clips are you running? I ask because I remember losing a metal clip (obd0 style) at the track one time, which left me running on 3 cylinders due to the injector being temporarily unplugged.

 

running fic 2150s all injectors are clipped

 

I use to have this issue because by gm 3bar map sensor would come loose. I'd look at you map sensor

 

I was think map sensor too but the data log doesn't show any signs of malfuction but I did but it used and had it for a few years I'll just buy a new one I need one anyways for my dd when it's done

 

Just for reference my data log didn't show a CEL or any signs of map failure

 

hmm ok understand. i just bought a new map sensor but car wont be at the track for some time im sending my tranny to dp for a g force gear set but i put a stock gsr tranny on the car and gonna daily it for a little bit i'll turn the boost back down to like 500ish
