sluggish throttle response no turbo fart
I have a 2007 ford f250 6.0l. it has a liberator egr delete, arp studs, stage 2 afe cold air intake that ive.taken out, banks hi ram intake elbow, bd elec, boost builder but it is unplugged, also has a innovative moderate FICM, 4" full mbrp exhaust, and fluidampr.
My issue is when i get on the throttle from a stop it takes a while for the truck to move i think it is from the egr delete but been reading that it might be the tunes i am running. i have driven a few buddies 6.0l 03 and 06s and they are tuned with erics extreme street and they dont act like my truck they are responsive. my truck when i first bought it use to turbo fart when there was excess pressure. after i got the tunes and egr delete it doesnt fart. in my buddies 6.0l when on the throttle and let off suddenly it farts unlike mine. i dont know if that info. will help at all. Also to add when the truck its in park and idling i hit the pedal and it takes a second or two for the rpms to go up. Also when i hold the pedal at about 2000 rpms and let off the pedal it takes a second or two to come back to idle.
I have learned to live with the symptoms of my truck but it always bothered me but now i want to find whats wrong with it. some say it is the egr some say it could be boot broken or cracked up pipe not aligned, ebp sensor, tunes, i dont know what it could be i wanted to try a tune of yours maybe it is the tunes. i have come to 2 conclusions, it is the absence of a egr, or the tunes. I changed the ebp sensor and that wasn't it. can anyone give me any info or advice??
