Here is a tune i have been working on and would like some feedback on it please. I will start a thread in the efi section regarding all my questions. I have been running it for about 3 or 4 years and keep trying to improve it and have seem to hit a wall. Stock tranny with transgo jr. never slipped. Runs good.

Well I'm pretty new to the efi live game and still learning. I really like looking at the calibrations people come up with. I find the amount of timing you run in the "cruise" range of the map interesting. According to my math you are running 100% of the main pulse BTDC, now I know advanced timing is good for fuel mileage but is 100% to much?

How did you go about making the desired boost map? Did you tune it based on EGT? Also it looks like you are running the turbo out to 32 psi, can the stock LBZ turbo take that?

You still use the stock torque reference map, Is there any benefit in changing that map to allow a higher torque request in the upper rpm range?

I see that you command around 29,000 psi of fuel in the high load/rpm range, combined with the longer pulse on the main injection is the stock cp3 able to keep up with that demand?

I'm sure there are some other differences I missed. I'm a little tired so hopefully this all makes sense haha
