secondary?s

[bradslt5]

took the wifes car out to the strip sunday for the first time .and going over the time slips saw that there was a 3mph diff in 1/8 mile speeds from 90.4 to 93.4. 60fts were2.005to 2.10 qtr times and speeds werefrom 12.31 to 12.51mph 113.86 to 116.78. i know there is a slow leak in the secondary system. my ? is could the secondaries start closing or be sticking part way open while going down the strip. i use my g-tech to download onto my computor and it shows on all runs i shifted within 150 rpms an all runs . does anyone have any experience or thoughts on this . i know i need to fix it but its going to be tough with twins on the way
