Need to know more about the injector info, and...

top of the morning to ya.

sorry, typical yank here.

why dont you tell us more about your vehicle.
engine, parts used, transmission, stall, gear ratio, cam etc.

your VE and spark tables are...

have you tried to start it at all?

this right here.
meth injection is nice, but, its not reliable. Over 100 degree temps, i get it, i live in phx, you cant be messin around, you lose that meth, you lose an engine.

sometimes it is easier to load in a stock LS1 tune file, and start fresh.
Especially if you are tuning an already bad tune.

and you always will on a street vehicle
you can never get it 100% perfect
Thats why we have closed loop and O2 sensors to keep it all in line

are you using the tire wizard or blue car software to change it ?

i dont have aprndl swithc on my truck. I have it look for what gear internally. There is a selection for that in the transission tab.
been like that for 5 years

So that answers the what question for cylinder #7....what about 1, 4, and 6?

sounds like you need to have someone else tune it for you.

post your tune and post a log of it running.

We cant do anything else until you do this...

i like using stft+ltft for the tables, but your st works just the same.
Dont go too high int he rpms, you dont have a wideband and you cant tune that high.
Also if you are logging spark reduction...

break in procdure?
its a roller cam engine, there is no break in.
start it, look for leaks, close the hood and get on the dyno for tuning.

Anything else?

if i paid $650 to have my truck tuned, why would i just give you my tune to look at?
Pay me $300 and ill send it to you.

This is why no one will just send you a file.

this make no sense

i love the sarcasm

i bet a few beers theres some awesome stories out there in 'toon' land..

like 45 hp loss aweful
