So i did like everyone said and I did a scan of my 98 gtp after my zzp install. zzp 1.0 ecm, cold air intake, 180* t-stat, 3" dp, straight pipe through resonator, 3.4 pulley. I was using a snap-on solius ultra scanner. At WOT it usually read .3* which i figured was due to the general condition of the car, mounts, suspension, etc. The most it saw was like 1.5*. Almost it was reading about 15.5* advanced timing at WOT, is this within the normal threshold??
