weird tps issue with holley 52mm

[BIGT94z]

well finally installed my holley 52mm. set the tps on .67 and it was 4.75 (if i remember right) on wot. took it for a 20 minute test drive and the idel started at 1000 then after 10 minutes was 2100 then 15 minutes was 3100. came back to the house and tested tps with the key on and it was at .73! what the hell. i know tps does effect performance if its out of wack and the car when ideling at 3100 was slow and getting to much fuel. any idea's guys? after dinner ima put it back to .67 a nd test drive it again i guess
