Obs questions, dam spelling

ok just rebuilt my 1994.5 psd. everything fresh, arp studs, rosewood stage 1 injectors, downpipe 4" exhaust, s+b intake, ebp delete pedistal and housing, stock turbo hpop and fuel system, the later of the three are going to be replaced soon as i lick my wounds from the build. I have a ts 6 pos chip but have not installed due to engine break in period. now my questions

i seem to have a hunt in the idle, its only about 75 rpm and rolls rather slowly, but it is very evident, any propbable causes?

I am going to run a terminator t500 hpop and regulated return, but not sure on turbo selection? ive looked at beans, considered a wicked wheel and 1.0 turbine housing, any input at all would be great.
P.s. i will be adding an intercooler soon as well

 

Not sure about your idle issue. But for turbo. A d66 would work well with those 1's... Installing a wicked wheel is pointless since you will be taking out the same thing you are putting in...

 

are there upgrade compressor wheels? i was looking at mine and it has some of the tips broken off.
