when i started my engine build i wanted to go efi but ended up rushed and $$$less so i threw a carb on it after a few test runs with the tbi on there. needing a little advice on what i should buy. i have my stock tbi and distributor, all the wiring it still in the truck. engine combo's not to crazy but it would idle good and run wide open (i imagine lean) with the tbi- everywhere in between was crap on stock tune. i would like to tune it by myself but i need it to run decent enough to drive and datalog -is there any resources for files/engine combos i may be able to use to make it atleast driveable and get datalogging?
engine combo is pretty much vortec longblock, lt4 cam, single plane, longtubes

We could assume, but need to know the ECM #, current bin's
They are labeled externally.

just went and looked on the outside it has a sticker that has:
Serv No. 16146299
i pulled it out and pulled off the accessable cover and couldn't read anything else inside of the ecm itself

If you haven't, download TunerPro free so you can get a look at your .bin's
TunerPro RT for datalogging & real time info from your truck.
Sources for stock .bin files:
moates.net/filemanager - moatesuser - moatespassword - gets you in.
DIYefi site - GM category.
TunerPro forum database.
You know that your truck screams EBL me.
Reading all RBob's tuning info on his dynamicefi site will really help you out.

yea the more i keep looking into it the ebl keeps coming to the top... i'm probably going to go ahead and order a wideband o2 and the aldl cable this week. i need to get my exhaust welded up and i already have the bung for the o2 to go in anyway.
