wow, how did you get 287 fwhp? stock is like 225 isn't it? 13.63@106? is this track or g-tech? g-tech usually tells you your going faster than you are. and 164 mph??? geez, even with a limiter of 150 ive heard that not all sevilles can do 150.
whats this Re-tuned Delphi ECM? must be one heck of a chip, im not calling bs or anything, but let us in on your secrets! other sts owners with intake/exhaust/bored out tb are in the low to mid 14's, your in the mid/high 13's.
