Finally will boost my Tib
Hard to keep track of what has and has not been tried. Keep reading conflicting information, but yeah if the problem gets worse as the fuel level goes down then its either a pump problem or the pump pickup is clogged or not able to reach down into the gas tank properly.

Don't start again...
The pump pick up is able to reach down and I know this for a fact. If its clogged please tell me why it's f*cking things up only at certain tps and at low rpms ?
Still waiting for the wide band to be delivered from UK. Tomorrow will have free time and will work on the intercooler piping.
A lot of sh*t coming my way , but I will make it work

Checked all relays today and everything was good ! Don't know what the f*ck is going on with this car?!
So again,
When the weather is cool the car runs ok 90% of the time, but if its hot ... oh boy ... bogs everytime when you press the gas pedal ! It does this only at low rps 2000-3000rpm and to go past this rpms you need give it a lot more gas. With more gas it misfires , shakes for a second and then goes. If you decide not to give it more gas it just stays quiet. It doesn't die, but no reaction at all !
TPS is ok, done the same sh*t with another TPS.
MAP sensor is ok
Checked the plugs AGAIN! They are new and brownish. Leads and coils NEW!
Crank sensor NEW
No vacuum leaks
O2 sensor is reading 14.6-14.8
Temp sensor is ok
FPR has been checked , but no by me.
Tried another set of injectors - same sh*t!
With the software for my piggyback I can monitor a lot of things and RPMs are not doing anything strange, so I assume that cam sensor is ok .
Tomorrow will try to find fuel pressure gauge to be 100% sure that the fuel delivery is ok.
I don't know what else to check... this stupid problem is taking my time instead of working on my turbo stuff.
If you have any ideas , please let me know.

Stock FPR. The only thing I did was pull its vacuum hose to check if there is fuel inside. There was only some smell of fuel. A guy that I know owns a garage so I left the car there. He wasn't able to connect to the ECU and I told him to check the FPR. i don't know how he checked it, but I plan on doing it myself.
Will do this test : Fuel test
Any better ideas

I have T connection where my nitrous was connected 
he wasn't able to connect , cause my car is 97'. It's not real OBD2 it's something called EOBD if I'm not mistaken.
I reset the ECU tonight I drove the car for about 25-30 miles and not a single issue, but the weather is cool and I drove it to a grill party outside of the city. We will see tomorrow, but I'm sure that during the day when it's hot I will have a lot of problems...

Have you checked your Intake Air Temp sensor? I believe its inside the MAP sensor. You'll have to look up the resistance specs to be sure what your meter should be showing between the Ground and Signal wires.
