i cant seem to find the damn thing. i think i do too cause i can hear a whistle that i never heard before. i replaced the IM gasket, TB Gasket, IM itself looked okay [no leaks]..now i noticed one bolt from the TB is missing and my maf is held in the intake by zip ties. would that cause any kind of issue?

yeah i think its going out. its getting harder and harder to start even for E85 and its like 80+ degrees over here so i know it shouldnt be getting the cold start issue just yet..it was starting up like a champ in april when i first put the 80s in on the 60s tune but now i have to prime it during the initial cold start. how would i go as to see if the pump is going? we just sent datalogs to vince, would he be able to see on that?

Those both could cause your problem, if it sucks in air after the maf (or around the maf seal.) When you get unmetered air after the MAF it can cause jerking. The ECU does not know how much fuel to throw in. It has more oxygen then it can account for and is trying to compensate.
what are peoples iat2 around for those running just a cobra h/e or any heat exchanger as the only cooling mod? mine can get up to 180 on certain 80+ degree day but will drop to 120-130 decently quick. pump was just replaced a couple months ago and cobra h/e was installed a couple weeks ago.

Just as I said a month ago... for the fuel pump, you need to check Fuel Pressure. Go to Auto Zone or Advance Auto. They usually have gauges you can rent... if not, then they should have one you can buy. Stock FP (no BRFPS, Return System, etc) should be 60psi, +/- 1 or 2.
Hooked up to the schrader valve that's on the fuel line that connects to the fuel rail. If you are on a stock fuel system (Pump and regulator) then you should be at 60psi, +/- 2 or 3.
