[QUOTE="svo/svt, post: 15609070, member: 108015"] I'm semi new to tuning with sct prp but I want to believe I'm fairly knowledgeable with tuning but I'm still learning the trouble shooting portion. The car 99 cobra on E85 5.0 stroker 11cc pistons Stock heads 3.4 whipple sbtb and jlt Ba5000 Long tubes 1000cc deatsch werks Fore return system with twin gt pumps Today on the dyno I hit a road block. My car goes lean around 5200 rpm. I've added fuel through the maf and added fuel in the wot multiplyer bit the conditions won't change. Fuel pressure stays steady which I figured the car would have ran out of pressure as caused the issue. I did notice that the maf airflow #/min flatlines at the same time the lean conditions occur. The maf counts are only 671.00 at 6000rpm. Any advice would be appreciated in guiding me. The car is still on the dyno and I'll be trying to figure it out in the morning. [/QUOTE]
