Hey folks got some strange stuff goin on here dont know if its boost cut or what? not throwing the code for it, just having problems getting back on the gas between gears, bad bogging and what not. and if i dont bog between gears i get a bad backfire before i reach full boost(24lbs) mindmelt rescaled my tune for 750's this mornin, thought that would solve the problem. oh i do have the tip connected.
Is that supposed to be a link to a log file? If so: A. the link format is wrong and B. it appears to require us to be logged in. The log file should be small enough to attach here?

Taking a look at your log now. You need to be monitoring ST knock and secondary to that, LT and TOTAL knock.
What are your mods and what's going on in the log? It'd be easier to start there then have to go through and try to piece it together. Are you doing pulls in certain gears? If so, which?
I need to get some sleep for tomorrow...I'll look at it more in depth in the morning. I'm guessing someone will come along before then, however.
Mods are in sig now, all the pulls are from 2nd to 3rd and 3rd to 4th. my biggest problem is that i cant get right back on the gas between shifts. sometimes if i powershift fast enough it'll work and car pulls like crazy but before i reach 24lbs it'll cut on me. cant be fuel cut, im not throwing the code for over boost so idk. but the car hits something cause i get a really big backfire and everything stops. but if i dont power shift between gears the car bogs bad and have to wait for rpms to come down before i can hit again. last night i was thinking maybe spark plugs, got them gapped at 35 maybe i'll try 33 today, i'm lost. i'll do some more log runs with st lg and tottal knock. which is better for you guys to read, the graph log are the dashboard logs?
Disconnect the battery to clear the trims and re-test.
Looks like you didn't clear the Fuel Trims after the Injectors were rescaled. During the crappy shifts your LTFT is -33% and the ST is -5%,,these maxed out trims look like cary-overs from when the ECU thought the injectors were much smaller.
BTW log the proper TPS pid to more easily see your WOT points

AFR's go lean at first around 14's and 13's at 4000 then taper off real fast to mid and low 10's by redline 6500. i see that i get 2.5 knock at most when it does that right 4900-5000 rpms. im not so worried bout that part as it only sees it for not even really a second.
