I'd stay right where your at, tranny wont hold much, and all the stuff you have done throwing a intercooler wont do much... you could put on things like a airdog, GDP big line kit, airboss intake or wilson thrasher, but I wouldn't do much to the injectors till you get the tuner you want.. don't want to over fuel the stock turbo and programing and once you have a tuner you dont want to under fuel it... I'd do the injectors when you get the tuner and set it up at that time...

It depends on your tranny.. Mine I think if I added 10hp it would explode... I also drive with a lead foot.. I have hear that 50hp tips are a decent combo without a tuner and stock turbo... and have heard of smaller but dont think they are worth the cost if the bigger stuff to support them isn't there...
free intercooler is a hard thing to pass up..
I'm sure you could squeeze a bit out of it before the tranny gave up the ghost before you are ready

I'm kinda in the same boat as you.. I want to put a tuner on it and get things going fast and more power, but I know I'll just toast the tranny... so until I put in a tranny in I'm just leaving it as is for now..
Oh and a boost fooler may help a little
