new guy here. was looking for some tuning advice for my 94' cobra. seems like every tim i drive the car and shut it off the next time i start it it runs completely different! i.e. popping, backfiring and such. other times it will act very civilized as it should. i keep good fuel in always and drive it maybe 400 to 500 miles a year. the consists of 347, trick flow track heat heads, trick flow r intake, trick flow stage 2 cam, t-trim, 50lb injectors with matching maf, msd 6al, complete aeromotive fuel system. still has stock computer, no chip! i know this may be vague but anything may help. my local tuner maintains that it shouldnt need a chip. also running 56lbs of fuel pressure and still cant get the car to fatten up.
