2005 5.3 silverado tune help

[Rmejia]

hey guys,

ive had the intune since 2011 and havent really done much with it other than installed the diablo tune. i have since installed, CAI, short tube headers, throttle body spacer, 3:73 gears (soon to be 4:56), 37x12.5x17 tires. the truck is a daily driver but used for desert off roading. is there anyway i can get a custom tune?

it is pretty sluggish on the take off, wouldnt mind some quicker firmer shifts, and my ABS and parking brake light come on after about 1/4 mile. i do only run 91 octane fuel.

hopefully someone can chime in and give me a hand with this.

the only files i have are my back up files that are stored in the tunes file. ill attatch it but let me know if anything else is needed??

And that throttle body spacer isn't doing anything for you. Could even be hurting. Performance. But lew can hook you up with the custom tune. Good luck. Oh and you may be better running a 4.88 gear with 37s. Especially if you ever pull anything.

yeah, get rid of that throttle body spacer.. doesn't do anything for ya.. gains you nothing.. those are an old-school carburetor trick and does nothing for newer fuel injected vehicles... it can also mess up the air flow and make things worse... so get rid of that.

and if you have a tune installed in the truck, then you should have 2 tune files in the intune tunes folder.. should be the original backup and the last tune written tune files..

if you only have that 1 file in there, then that's not right.. contact [email protected]

if you did not complete the tune install, then no, there is no tune installed in the truck..

connect to your truck and select/install one of the preset tunes.. then you should have 2 files in there...

thats super weird, i pulled a bunch of fuses and did the tune, i could have sworn it installed.

so i went ahead and updated my intune and installed the diablo tune, after pulling most of the fuses it finally installed. i brought the intune back inside hooked it up to the laptop, went to the tunes file and there was a back up tune file and a second that i beleive said recently installed?? so i went ahead and renamed it and added -diablotune-11-12-2015, hit save and i saw something pop onto the intune screen then go away, then i noticed the recently installed tune was no longer in the tunes folder, did i do somehting wrong??

[Egoresb]

Not 100% sure but if I were to guess it reloaded the tune into the intune as a custom tune when you renamed it.
