Nobody should run as low as 2" on a 92/93 unless they're intercooled or water-injected. It'll actually kill power. Way too extreme, even for my setup.
On your Jet, I heard that they didn't make a chip for the 92 SSEi? Or is that what the 'custom' was referring to? I know there are some other 92'* here that might be interested in that.
You may also want to switch to a gatorback belt in addition to that zzp idler. Just to make sure. The 2.2" pulley is dinky, and you need good belt wrap. You'll be running a similar setup to mine, and if your chip raises your redline to where mine is, with that smaller pulley, you'll be spinning that SC at over 16,000 rpm'* at redline.
Get that sucker flushed, too. And clean your TB.
