I own a restoration and custom build shop. I am new to tuning and i am having trouble getting this LS swapped 1987 monte carlo running again. My tuning guy has left me high and dry and now i am trying to figure it out myself. I had it running enough to drive it around the block but now with that same tune it will not run. I have changed the tune and made adjustments based off of another LS swapped truck i have with a stage 3 cam. That truck runs decent enough to drive it around but i still cant get this monte carlo to run like it did before. I have attached the 1st tune that had it running and the 2nd tune that i have done. They are labeled 1st and 2nd tune. Any help would be greatly appreciated. This is a rebuilt 2005 LM7 5.3 bored 30 over with a sloppy stage 2 cam, cold air intake, stock torque converter and long tube headers.
