Hey guys, just wanna see if someone could help out here.
Gonna start tuning soon and was hoping, since there's a LOT of turbo trucks here, if someone would be willing to share their tune file so I can hit the ground with something atleast somewhat close to what I want to be.

Ofcourse every kit is different, etc. but a tune with a starting point would greatly help. Using a 7875 ON3 turbo on a flipped manifold kit with a Tick stage 2 turbo cam in a 10:1 comp 5.3 with stainless valves/dual springs/4L80E and a 2.5bar sensor



I know some people have spent good money on tunes and may not want to share (or can't) but I also know some have done it themselves. I can def. compensate you for it 'cos it'll def save me a whole load of time.

Thanks!

The repository is all HPT do can't really use. May be able to get a idea of what the timing table looks like though
Thanks

Hey just saw this. Also started a new thread as I forgot this thread; will delete other.

The issue we're having is that the E38 is such a bastard of a setup it's not as straight forward as the older LS1s. A friend of mine who used to be very good at the older stuff came out of tuning retirement to help me tune this truck and he's scratching his head too!

At first, it was too damn rich and the WB was spiking lean. After a change of plugs and double checking everything, and leaning it out, it still has a mind of its own. making 7psi with boost controller off at about 2500 rpm. I have many logs and can send you tune if you wanna look at it.

thanks!

I'm dealing with a lean spike as well. Hits every single time about 2 seconds after boost kicks in. There must be something we are missing....
