ok, so I have a LQ9 408 ci motor 10.9 compression heads with texas torquer v4 cam high rise intake with 102mm T/B. i have been working on the tune myself and thanks to everyones help on the forum, I have learned alot and was able to tune the vehicle myself. I did go to a dyno shop to clean up my tune and get a good dyno number 470HP and 430TQ. but my question is I noticed on a pull the engine reads knock and pulls timming but I cant figure out why??? I have recently went to a Track Day event and engine felt very good added 101 octane fuel and did a log an noticed its still reading Knock on a hard pull?? Also noticed my dyno numbers on HP Tuners are much lower than the dyno...maybe my formula is incorrect??? but double checked it seems correct...
SO to those of you who have WAY more knowledge than me please look over my tune and log and please tell me what you guys think??? what to make sure my dyno tune is done right.... and didnt just pay money for nothing! the tuner did tune it in open loop and I changed to back to closed loop. just my preferenceCutlass after dyno tune with ltft.hplCutlass tune after dyno with LTFT.hpt.
