Time slips and ZEX

YeeeeHaaa! I got a SVX last Friday. Pearl and black, 127K with a SOA reman. tranny in the last 20k. Got all the papers to prove it too. Fair amount of dents and dings though.
Went to the track tonight, 16.5 time slips consistently. Three runs all at 16.5XX at around 85 miles per hour. Not bad for a heavy beast. Was kicking import butt, except for a GS-T running 14.7.
I waant to install a ZEX system but have a few questions. Dosen't the SVX TPS work opposite to what the ZEX control box needs? ZEX must see above 4.2 volts at WOT, I thought SVX was 0 volts at WOT. Where should I place the nozzle in the intake track? Any answers would be appreciated


Thanks
