I am trying to run low boost (15PSI), to start a low "tuning curve". I have a TE63 and 72# inj and 2 307 F/P's. Base fuel pressure is 40 and I see 55-60@WOT. The problem is at WOT, the car pulls, pulls, pulls, and then fall flat (FP is 55-60), then picks up and pulls, pulls, pulls, falls flat, then repeat. Knock is >5. I do not get this problem at 1/2 throttle. Why is it falling flat at WOT?
I have the wastegate rod turned all the way out. It has 3-4 threads left. Is it possible once I hit 15 PSI and the wastegate opens the loose end (due to too few threads) is flexing and causing the surging? Anyone experienced this? Is this a possible cause? Any suggestions?
