I have had my GN for over 6 years now. Started by making it look good, it had spent it's life baking in the AZ sun. Last year I had a guy build me a stout short block. Ported heads, custom ground cam, RJC power plate, diamond forged pistons....I wanted it to be very streetable, wasn't going to go to the track often, but it would be nice to bust off a 12 second run every now and again like I have read about on the boards for 6 years 
I ordered up some new 42.5lb injectors from turbo tweak and got a matching chip. I was all excited to break this thing in and hit the street. The car runs awesome, but lacks power out of the hole, and sometimes it doesn't even like to boost once it IS out of the hole.
I thought I possibly had an exhaust leak, could hear some ticking and the manifolds that I put on after the rebuild were welded up during the rebuild. SO, I buy some known good manifolds off the board here and even find a good deal on a 3" THDP locally. This fixes my exhaust leak and eliminates the old downpipe, I should really be cooking with fire now, right? Still same issue, car starts right up, sounds awesome, but can't get out of it's way from a dig. I had the trans rebuilt before I did the motor, I had ran the trans with the old motor and the car seemed faster with the oil leaky bad seal tired azz motor. I don't believe my issue to be the trans or the converter (however I am open to it being the converter which I bought at time of trans rebuild 2600 stall).
So, I'm sure you are all asking at this time, what the hell turbo are you running. With the new short block I basically was suckered into buying this turbo he had with the motor, "oh, it's a great old skoool turbo, will be great, yada, yada yada". I'm told it's a stage 2 turbonetics cheetah turbo. Now, based on everything I have told you up to this point, what the hell is wrong with my turd of a GN? Have I beat new vettes from a roll in it? YES, when the damn turbo decides to spool. However, do most of the time I get taken to the wood shed b/c I can't go from a dig and even from a roll my turbo spools when and if it thinks it's time! I believe the turbo is my problem, I'm sure you all do too. SO, what turbo do I buy? Could there be another issue? Is there anyone in metro-Detroit that can help. Is there any point in getting this thing tuned before getting a new turbo. I'm about done throwing money at this car and can't stand the lack of consistent power. Based on what I have done to the car, with MUCH MUCH MUCH reading, I should be blowing the doors of stock vettes all day and night. Thanks for listening and can't wait to hear what you all think.
Thanks,
