Default I've got issues

...which is to be expected. I took the SSEi on a fairly decent drive yesterday, and since this issue came up http://www.bonnevilleclub.com/forum/...121&highlight= , and correcting it, I have had some massive loss in power. Boost often dumps, and I rarely hit my max boost. So far, here are my findings through the scantool:

IAT: It climbs all the way up to 140ish. The sensor is located close to the exhaust crossover, which I know is NOT the ideal place for it. I'm going to reloc it, but how just how much of an effect does the IAT have on fuel maps?

Temp: Yeah, that climbs too. 220ish. Been looking in the FSM for the spot to tap into for a happy switch, and I think I found the spot...in the 93 FSM book 2, page 6E3-a-9, it appears GC3 is the place to tap to ground. Is that the spot for those that are running the overide? I used to just turn on the AC, but now that it all leaked out (fairwell ice cold R12), the fans wont come on unless the compressor kicks in, which it doesn't.

BCS: Appears to work as it should...up at idle, down when snapping the throttle. Funny thing though...the FSM states that it bypasses when put in reverse, which makes sense. Mine doesn't. Which leads me to think the system is flaky.

Also, my tensioner is a bit on the weak side. As a temporary measure, I put on a smaller belt, though not by much. Will this cause sc slippage?

EDIT - This is a bit of P&B, Forced Induction, and 92-99 all in one. Mods feel free to move to the most appropriate spot, wherever that may be

EDIT 2 - Found part of the problem...silly me didn't swap the MAFs back between the models. What a difference that made

That MAF sensor is going to be a BIG factor. You were running way lean, which was also causing your coolant temp problems to a degree. Relocate that IAT. There'* at least another 10 degrees of timing.

I put everything back the way it was prior to swapping bits and pieces around. My boost came back Scanned for other little tidbits, and only saw 1 KS during the entire drive.

I will be relocating the IAT to the outside of the engine bay on my next work break. I am still going to do the fan bypass as well. But does anyone know what the BCS is supposed to act like when in reverse? My books say one thing, and the car is doing something else.
