as for mileage that is the bad part. since i had my PCM done by someone that fucked it up so bad i cant use it or i pop codes left and right. so i borrowed a PCM that has a tune for a 408 so it would ge truck to run. but it runs extremely rich. im so rich that i look like a diesel when i give it anythine more then half throttle. i mean it runs but my A/F has to be in the 10:x range. i still get 13mpg tho. i know i can get alot better if i had a tune. gears help beleive it or not but city driving will always be bad cause of the stall. but that 13 is mainly city driving

 

damn do you granny it in town?? or do you live in a small town because my truck w/o any mods gets 14.9 according to the pcm. with a cr of 11.9 can you still run pump gas?

p.s. how many horses at the motor do you think you make?

 

me babying my **** lol thats funny. nah man i drive it like its meant to but if im in stop and go of course i cant get on it. im at 11.0 right now and 11.5 is what ppl say is max

as for hp at motor well easily over 400. i cant really put a finger on it to i run it

 

also when i was a 5.3 with K&N, flowmaster and Efans i was seeing anywhere from 18.5 to 21mpg average. the higher was with a clean filter and slightly more highway this was with A/C on and of course how i drive

i also dont live around flats, alot of hills and truck is around 4600 lbs and ran that on 93 octane. seen less on 89

 

thanks for helpin a i really dig your truck.. i wanted that cowl hood but now 2 many ppl around town have one so i said 4get it.. thats a reflexxion right?

and if you dont mind sayin.. whats your mods. the motor of course. and the efans? did you upsize the rad or stay with the 5.3 rad.(or r they the same size idk.. ..) if i did do a built 6.0l swap i would definatly upsize my rad. bcuz im coming from a 4.8 to that. did you swap out pistons or did you just mill the heads??or a combo of the both...

 

its a GM hood.
its a LQ9 shorblock so it has the better internals along with flat top pistons

i have the larger rad with the oil cooler. yes efans, built trans, headers no cats, super40 flow,410s, the list is long and too early right now. its on here in plenty of places

 

do you have a sniffer or any kind of testing in PA.?

 

hey man you wanna sponsor my truck with your motor?? haha

 

no sniffers just emisison testing and in modern world all they do is hook up to your OBD port and see if you pop a code if not then your fine

 

i odnt think my sponsor would be happy with that one.
