Default LS/vtec; 12:1 compression; stock cams. Tuning question?

What timing maps are you guys basing yours off of? I used a base p30; p72; p73. All of them which the car still feels sluggish before vtec; I swapped in a friends ecu which is dyno tuned; Not sure what map its based off of; But it runs alot better. I think I see upwheres of 28-31* at WOT. Car is tuned on crome pro also.

Any tuners insite?

Motor has over 4k miles on it already; limiters at 7500; shift around 7200 when the CEL pops up. AFR's are anywhere from 14:1 to 12:1 throughout the whole tune as per the LC1 with crome pro.

edit: for the hell of it; dont mind the shitty intake/header.




EDIT IM STILL TRIAL USER AND CANT POST MORE THEN 5 POSTS; hahah. This is a ls block; usdm STD bore b16a2's, obd2 oil pump; stock b16 head; blox manifold; ITR throttle body. Other setup is a 01 gsr longblock; ITR cams; s2 manifold/s2 throttle body; Mugen 4-1 header.
