turbo actuator question???

i recently smoked my T25 in my 91 9000t. i replaced it with a T3, but to make the actuator clear the balance shaft i had to weld longer bolts on it... this method killed the internals of the actuator.... so i walked over to our pile of junk turbos, and grabbed a t25 off a 9-5 and robbed the actuator off it... welded bigger bolts on that and threw it together.
now the car doesnt seem to boost right. at first i had the baseboost way high (legthening the bolts did the same thing as shortening the rod) so i brought it back down to 5-7 psi. the car is having an awful hard time maintaining boost as by 5k it has backed down to around 8 psi. i think my t25 was holding up better then taht.
so would anyone say that the smaller actuator off the T25 is letting the wastegate get pushed open. should i fit another T3 actuator on there.
