I vote for a boost leak.

A few months ago, it basically stopped working where I thought it was electrical with no signal, but some DLL logs show odd results and I believe signal is fine. Below is a segment of a good log from the past where the WG is closed at 98 up to right before WG RPM (3600).

Its almost as if it thinks 152 KPA or so is the boost target, but it is not based on the recorded zone settings. Not sure where to look at this point. I checked the pressure signal hose to the EBC, but a leak there would likely cause over boost not underboost I would think. Any one have a similar situation in the past? I have no problem replacing the EBC with something FM has for sale, just want to try to identify that as the problem before playing musical parts. The car still runs great, and 8psi is better then 2psi...it just feels off. Slow if you will. Y'all probably can empathize with my problem :) cheers, - b Old log zone settings: Initial zone map 24 74 73 194 40 203 39 22 17 92 22 34 40 25 50 36 12 10 42 42 12 20 16 15 14 13 76 77 80 88 90 91 67 69 76 82 70 86 70 69 69 66 73 68 63 67 66 66 67 67 73 76 78 80 79 79 81 90 90 81 75 71 74 75 85 100 97 82 77 80 79 77 79 99 97 82 74 68 78 78 98 98 98 100 103 103 104 105 113 122 124 125 125 122 120 117 118 118 118 118 114 114 118 125 130 134 137 137 135 132 129 125 10 18 128 128 128 128 136 140 147 151 154 156 154 152 148 140 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 40 40 52 77 81 120 124 127 125 120 118 121 124 126 128 130 40 40 64 104 114 118 121 123 122 112 107 109 112 116 120 124 40 40 80 98 104 106 108 104 100 98 100 102 104 106 110 114 40 40 77 94 100 98 90 81 73 70 74 80 86 91 95 99 40 40 60 80 85 78 68 59 52 50 53 57 62 68 74 80 20 25 45 52 55 53 46 38 33 30 34 38 43 48 54 60 3 198 27 65 103 180 180 180 180 180 180 180 180 180 180 180 1 84 117 114 98 111 32 49 15 64 16 25 128 128 32 32 ATM = 103 Chip ID = MK-2 12FEB2002 New log zone settings: only a few fuel rows are different, and ATM.
