lbz tuning questions

[redws6rocket]

alright i need some help guys. here is what i am trying to figure out, i got my 4088 on and pulled with it the first time last friday, i logged my pull and noticed around the time the truck would shift my main mm3 would drop down to around 80 which it normally runs around 100. when that happens my injector pw goes down as does timming. what would cause this is this a defuel problem or do i have something else going on. the tune is one that nick sent me to get started with my gt40 i have not touched it all. please any help or ideas i am all ears.

Charger possibly off on the shift , you might try raising your shift points a little and then log it to see if it still happens

Sounds like defuel to me. Defuel cuts flow mm3, lower flow mm3 cuts PW and timing.

I agree.

hey nick i ran your sledpuller tune about a month ago and it drained my rails......

Curtis,

It looks like you also downloaded " LBZ_DT_HOTV2.5.tun", I would run that and if you continue to have rail drainage issues please send me an email directly. I'll help you troubleshoot from there.

Thanks

Nick

yea i like tunes :rofl: i messed with your sledpuller tune a lil, well just the PW table and pulled it, it was nice would have done better if i had better tires and was smokin ppl in dirt drags, i like your timing i run it in my DD tune and its very well behaved but still has power and gets decent MPG for the way i drive....o and my avatar is the pull were i ran your tune....heres a vid of the pull i did with your tune were i adjusted the PW.
