this gonna be long winded,sorry for that. origanally i had a dyno tune with a jaybird j3 (moats) chip.i had 19 lb injectors with a 70mm maf. i was shooting a 125 shot with it and i do have h/c/i so the injectors were way maxed out. i then switched to a pmas 95 mm maf and 30 lb injectors and my innovative afr guage was reading i was leaning out at wot. i then had a buddy change a few parameters on my tune and reburnt my chip. now erratic idle at start,adjusted blade wont be erratic , but 1100 idle. switch to two position on chip for nos tune ,get check engine light now i went to start it after putting the blade back and it will start and idle perferect but only once. if i try to start right after just turns over. if i feather the gas at start up it will chug up to idle then stay there and run fine. i have no clue about tuning but i did watch him do it and he just changed the base settings of the cars fuel system. if you want to read my tune let me know as i can bring it up and maybe do a copy paste thing if that works. or do i just have a mechanical thing that i have to go through,the only thing is it ran perfect before but it has sat a few months inbetween playing with it. i did check the tps voltage ,fuel pressure etc. while it chugs up it runs rich about 12 to 13 then flatens out at idle to 14 -15.5 afr.
