You're ok. I like this 
You're not going to get a whole lot from a stock chip and cat converter in place on stock tires. The minimum you're going to need is a decent chip and some good tires with a high flow air filter. If you want to turn up the boost, you're going to have to see how much the cat is restricting it, because you may be just wasting your time if you're cats causing boost stacking. A 160 thermostat wouldn't be a bad idea either. But don't beat on it unless you have a scanmaster and an RJC power plate on it.

Yes have a scanmaster and been working through the items one at a time. The car is new to me in Feb (I'm second owner), car sat for very long time and I had to go through everything (first fuel filter change, etc.). Finally got it running good. I have a TT chip in it now, but will go back to stock to see just how well it will run with it. I'm running 93 octane. Initially I needed fuel pump and hotwire to be able to run 12 psi without knock. Now inching my way forward. As there seems to be a number of these cars in the 12's, 11's and quicker I don't have aspirations of going super quick. Just want the car to run as well as it possibly can while remaining relatively stock. I struggle with pulling the cat for example. But I totally understand the point on more boost in with no way to get out is silly. I just want her to be tuned as well as possible on the boost I'm running. almost harder to leave stock than to modify, I'm trying to keep her fun, reliable, as effortless as possible and yet still retain the value as a car easily returned to stock.
It is clear I won't be the quickest turbo buick, but I'm good with that. It is also rather inexpensive to tune down here at the stock specs.
Thanks,
Joel

Take a straw and put a cotton ball on the end. Try sucking through it. Now take the cotton ball off and try it again. Let the engine breath and it will perform better. There are 'tricks' to do it that are less obvious to the untrained eye but the bottom line is if you want to go faster the engine needs to breath in and exhale.

You don't have to put the old chip in to see how it runs. Just take my word for it. Leave the TT chip in. The factory stuff didn't really run that good. It was sufficient, but not efficient. It's ok, leave that converter in-it'll still run good. Just leave the boost at 15 psi and get the launch down to a science. Good brakes and good tires.

would be thrilled to get to high 12s with cat and stock injectors and the like
i will continue to tune and see where i can get thos fall when the air gets nice and cool
clear tires are huge limitation and as guys have made clear i absolutely need drag tires.for rear to get true performance assessment
last time at track i could launch woth no more than 4 pounds and even at 3-4 if i mashed after letting up.on brake i went up on smoke. pronto had me roll into throttle off line and that was best launch to date at the 1.9 60

I think it's possible even with the cat. But a little more boost will be needed if you can control the KR. Good luck keep us posted.

the stock chip has 22 degrees of timing at WOT. WAY TOO MUCH for todays gas and what you are doing. couple that with less fuel and you will by buying head gaskets soon. Put the TT back in

Yep. They did it with timing back then. Though, their premium fuel was soo much better in 86-87 than ours is now. You can't get away with that now. Put in the TT, AFE air filter, 160 t stat, real slicks, race fuel, and turn up the boost. You'll get it then. Though don't over octane either, it's not good. Not as bad as under-octaning, but nonetheless... Ensure you have zddp in your oil. And if you're trying to stay stock, where'd that vacuum brakes set up come from? There's half your launch gone right there. And re-check all vac sources, to see if you have any vacuum leaks. I'd also tape a fuel pressure gauge to your windshield while doing a low boost full run on the car to see if your pressure's doing what it's supposed to be doing. Or you could temporarily wire in a wide band o2 sensor and have a passenger watch it during the entire run to see where it's at.
The things you mentioned are the usual suspects to be upgraded 1st on most cars, especially forced induction cars, because of cost and ease. Often times these are considered to be factory installed bottle necks.
To each his own tho, some guys like your self are just a little more hard core and make it a point to see how far one can go on these parts.
Its all in good fun tho, and it is pretty cool from a street racing stand point to get away with the old, "its stock" seeee look under the hood.

It's what I'm doing too My car's (if I can get the tune down) going to be really fast, with as little external modifications as possible. The only thing I'm not trying to hide is the exhaust but other than that, it's all done up. Or will be when I'm done. Ported tb/dog house/manifold/heads, cam, forged crank, girdle, bigger stealth intercooler, all stickers in place, the whole nine yards. Besides the pressure regulator and down pipe, you'll have no idea....

People that don't know anything about Turbo Buicks haven't got a clue what they are looking at anyway. You may fool them but anyone that has any knowledge will see though the smoke screen.

You can tell I have a TA61, cam, and ported innards? How. I mean, honestly, there are no such things as sleeper GN's, granted. But I can fool most people. I have attention to detail you've never witnessed before. All I gotta do is find facts, and I can OCD something to death.

Yep.
Only 15psi? Don't gamble on winning that bet.
Several of us can hold more than that with our PM systems..
I've held up to 17psi (60's didn't improve from the normal 15psi) and a buddy launches at 18psi foot braking it.. He's been 11.8's with his GN and 60's of 1.53 with stock turbo, stock IC, stock injectors. He beats the hell out of it when racing it to get the ET.With all that said the 60's are critical to good ET's in my car. My car can will not ET at all unless the 60's are in the very low 1.6's.

I've done 17-18 but 15 is really all I want/need to do. With slicks on 20 would not surprise me. A good vacuum system with the right brakes is just as good.
