I'll try to answere your questions. I am not a pro or even close to it but i may be able to direct you to the answere. The ltg true tuners are few. The really good ones have moved on due to the community.
1st ltg are very delicate engine and you may blow your baby up at any time. So when adding to your tables do more reasonable numbers and slowly work your way up. You may be putting in numbers that the engine will try to do..... TRY!!! It will probably do more wrong than right. Our cars can't make huge amounts of tourqe from dead stop due to weaker components that limit us from torque. I have a awd. I have not looked at your tune but off the top of the head if you touched the accel threshold and comanded torque delta you are looking and limiting your power.those limit rate of acceleration , How quickly it increases torque and how far before you hit rev limiter. You never want to touch your Virtual Tourque unless you really need big changes but stage one you shouldn't. Our cars have so many sensors that when you change those numbers its gonna try those numbers and make its own numbers to compensate the difference. If you have a afr gauge it will help you tune. So if you don't have one i reccomend you do asap. I've paid your allot of tunes and made allot of tunes or dialled in my tunes i bought. So just don't let anyone tune your car. Its not like a LS at all and many people do not know these engines well enough. Even in the US. I will look over your tunes when I have time. Start with the tables i stated. And raise in small increments. Good luck.
