Good day all, I've totally rebuilt a 96 GMC Sierra K1500 over the past year with the following mods;
New HT383e engine, rebuilt/beefed up 4L60e (I know, I know - should've 4L80e'd it), rebuilt/beefed up rear axle and added Detroit helical locker, 6" Procomp lift with 35x12.50 BFG All Terrains, etc, etc, etc, etc, etc, etc, etc,..... the list is extensive,....basically, no bolt/nut left unturned.
Additionally swapped the ECM to 0411 (with the above mentioned 2002 Express van base tune already installed from Lextech).
I took it to my local tuner/dyno'd tuned the truck (got good numbers for a 4WD truck),......then, purchased HPTuners so I could play a little with it too.
Problem now is I need the requested base tune to bounce baseline against all the changes made to date. I've looked in the HPTuners repository, there is a factory base tune for a 2002 Express van with 5.7L but, it has the 4L80e (I need the 4L60e with 4WD version). I've also looked online (a lot), but can't find one. I found on gmtruckcentral they have the base tune I need but, its EFI-Live based (not our beloved HPTuners). When I tried to download/open from their site, HPTuners said "wrong file name" or something like that.
I know a lot of these year trucks with 4L60e's have had the 0411 swap,...any of you guys have the base Express van file or, maybe point me to where I can get one? Someone asked me for my tune a few weeks ago, but, I knew it had been heavily modified thus knew it wouldn't serve what he was looking for.
Much appreciate y'alls help guys,....this is a great forum with outstanding experts in the field.
