Help!
New to Ty-land here. Here is a brief low down on ty.
1992 146K Bought 2 monthes ago. within first 2 weeks fuel pump died. Lines were too far gone to salvage. Ended up buying new tank, sump kit with MSD inline pump. Alum line with Russel filter. It has 40 psi at idle, and psi goes up to about 45 with a blip of the throttle. In the process I have replaced the inter cooler lines, and a Johnson pump from Ron Gregory showed up today.(not yet installed) vehicle has been running and driving fine. It has been back on the road for a grand total of a week. It has cr42ts, accel wires. unknown cap and rotor. stock appearing coil. On the way home today it started missing and hiccuping.

Today I pulled intake tract, and TB and cleaned from end to end. also checked vacuum line diagram in another post and ran all new vacuum line. My lines are fine except I have an extra check valve compared to loeryder's diagram. I have a check valve that has an extra port of at a 90 degree angle. So I have an extra small check valve for some reason. I also found a wire that has a crisp spot from sitting against head shield that may be causing miss. I cleaned and taped it up until I can afford new wires. After I get it all back together, and take it for a test drive, when I get into boost at roughly 10lbs (stock gauge) it hiccups and hisses. Other pertinent information....Flowmaster 3 in dumping at axle, and no cat ( i did it before I read about the negatives....I will resolve shortly) K & N filter in stock box.
I know this may not be enough to thoroughly diagnose, but hoping some of the veterans can move me in the right direction to investigate.

I have read the list of the "first things to do" modifications, and am working down the list. I am going to follow the list of modifications that they syty sites are listing. But I have to get this this to get me to and from work to earn the $$ to be able to modify and improve.
I do not have any kind of way to do the data master or any of that. I have the laptop. Can I download the program from somewhere? What about the cable? It is not throwing any codes.

Last Q....who is the key vendor for in cab boost controller? to cover my but without the converter. Is in cab more common or one under the hood. I have someone offering the under the hood job (turbo xs? I think) for 50.00

SORRY for the extremely long post. Thanks in advance for the help!

I wouldnt continue to test the lack of being in-tune.. be nice to her.
The burnt wire is a good indicatior of you sputtering problem, I'd start there.

the check vavle with 2 outlits is stock, and correct. There are 3 on the whole system. 2 along the left side of the manifold, and one at the front.

and a note on the boost controller & cat situation. typically the bad responce caused by the cat removal is a result of the small and ineffective wastegate combined with high pressure in the exhaust system.

A different controller may be able to do some magic, but dong be surprized if it doesnt.

How would I know if I have a wastegate issue? Is there some way to test? It feels to me like a waste gate or bov when I get up in the boost because it lays down and an accompanying whoooosh. I will do some searches for waste gate info to see what I can find.
The exhaust that was on the vehicle was stock replacement stuff, but nothing I would consider extremely restrictive. I have the previous owners recepts showing a some what recent cat. I don't want to overboost or have the boost spikes that I am reading about.
Any negative issues with MSD stuff? IF not I have access to the entire line through work.
