im trying to tune a buddies truck and i just cant figure out why the hell he is so sluggish off the line. tm is removed for the most part i think? i dont know if its because its a big truck w/ a little motor or what???? take a look and let me know what you think.

4.8 cc 4X4
g80 w/ 3.73s

 

What octane yall tuning it for?
Do you have any logs?

 

yes. low octane.

 

ok son of a bitch i have to type this **** again.

its a fat pig wih a little pecker lol. this is the reason we told you not to get a 4.8. only thing i can see is timming. play with timming and fueling with the wide band.



sorry about that i had typed it all in and hit post and i lost connection and it deleted it.

 

next time you hook up the logger use the laptop and hit play and reset fuel trims. you have a long term fuel trim causeing the truck to stay rich at wot in pe.

the litle button at the top that says on/off/100% click that, then fuel&spark and on tht tab click reset fuel trims.

 

alright. no need for the abusive language.=)
