hey everyone wondering if anyone has done anything with the new 5.3l direct injection engines yet? I have cat back exhaust and a cold air intake on the truck rite now but want to do some transmisson...
Hey everyone,
I bought this truck two years ago and am awful tired of being the slow one on the block.
I need a tune... Badly. Would anyone be willing to give me some help? Its on a 2013 gmc...
It is probly my best bet to leave it be i guess. :unsure: Was hoping to get rid of that pesky speed limiter. Ill probly leave it alone for now make sure its not a warranty pig, maybe tune it later...
Hello everyone.
I have just purchased a 2013 gmc sierra with the 5.3l flex. I want to tune this pcm but am not sure if it leaves a history of flashes like the duramaxes do. I do not want any...
Hey John
I never did figure out this problem... I moved up to forced induction and had a friend tune in a custom operating system for it. I do know the problem was with my injection pulse though....
So far im looking at http://www.alcohol-injection.com/en/corvette/49-ls1-7-stage-2a.html

What size
Meth jets do you think I should go with?
I beleive the next spring I have is 6 pounds. I bought several springs extra when I got the kit. I'll look into spark plugs today.
I plan to run 8-10 psi boost in the end, nothing too radical. Yeah meth is a must on the engine. I am running a 340 lph pump, I have a spare inline fuel pump I was going to use on another project...
Awesome! Coming that good eh? Are we ready for more boost? Meth kit will come when i get back from italy possibly late november. Ill probly have two tunes for normal boost and high boost high octane...
Here is another tune. Hope this works. first one i tried computer died and didnt save. second one i was on the side of the highway. Caught a jack handle off someones truck and poked a 1/2 inch hole...
Just a quick scan theres quite a bit more information on here than youd find in a normal manual, or alldata for that matter. I think i may just print this off for a go to when even working on other...
Thanks Joe im gona read up. make it a file on my cellphone so when im sitting on a site waiting or in camp im not wasting time. :book: The things I get paid for....:lookaround:
Thanks Joe. I wish I was as knowledgeable as you guys. How do I learn about this stuff as you guys did? Thanks again guys. :good:
AWESOME! Man your my hero. I figured it was something bad at first. :ermm: Thank goodnes it wasnt. Ill load and log as soon as I get the cable back. This is going to be a long 15 days...
Frame 1790 is when it started to act funny and had no power like someone shut the key off.
I only have a 3-5 psi spring in the gate. Hmm wonder why wideband didnt log... It cut out in 3rd gear at about 180 ish.
here is another log. The first bit I manual shifted from 2nd to 3rd. on the next higher boost run I let the truck do its job.
The first one it went dead, i hope the logger showed you. Its like it...
Ill get one more run in today, and ill give you some wot, im gona keep a close eye on the timing though dont wana get too high there,

DOH! Howd i manage that! Yeah leaning out that fast kinda scared me. haha.
