first thing you need to decrease the amount of fuel in columns 7-10 in rows 5000-7500 this should remove your flat spot. Other thing is, since you have all that head work you should lower your vtec engagement point to atleast 4800, you should post a datalog though

I did some changes, you will need to adjust for idle and leaning out the tables where you cruise on the highway. lmk how it works for you.

Thanks for the input man but that map had way too much timing all over the place the motor starts to ping at about 30 degrees of timing usually under a full thorttle load it responded good to about 27degrees of timing
