I'm glad I don't have to buy another one too. I need to try and sell the other LS2 and ported LS1 throttle bodies I have. Don't need 3 throttle bodies.

I guess when this is all said and done, I'm going to have to find a dyno somewhere to see what the engine is REALLY putting out. With all the issues I found since bringing it home, the dyno sheet that Aaron generated really can't be telling the true story. Heck, just this incompatible throttle body could make a substantial difference, I would think. And those exhaust leaks would certainly affect the turbo boost. No telling what those clogged fuel injectors were doing.
Certainly I would hope that a GOOD tune on the engine would clean up that graph and put more power down on the lower end where it would be most useful on the street.
I just don't know of anyone locally with a dyno that I would be comfortable taking the car to when this is all finished.
Speaking of finished, maybe I should detail what remains to be done to keep myself straight.
- Install fuel pump when it comes back from Lonnie's.
- Install new fuel injectors and put the fuel system back together on the engine.
- Adjust the new fuel pressure regulator.
- Install vacuum manifold block.
- Relocate vacuum line from front of manifold to the vacuum block.
- Hook up vacuum line from FPR after setting the pressure.
- Run the vacuum line from the modified fuel pump to the vacuum block.
- Install the new throttle body when it comes in.
- Fill up a gas tank or two and put some gasoline into the car's fuel tank(s).
- Make sure everything is TIGHT.
- Cross my fingers and do a "smoke test".
- Check for fuel and vacuum leaks.
- If everything appears to be OK, relocate the 2 bar MAP sensor to the front of the intake manifold.
- Time to do the tuning and hope nothing crops up to make all of this a complete waste of time and money.

Ryan @ SS Performance would probably be the closest....

I asked Ryan for help with my fuel system back in January or so. He apparently is not interested in acquiring my business.

Did you happen to ask Kenny when he lent a hand? If not, I'd give him a buzz.

No, I did not. At the time, I thought I would be hearing back from SS Performance, who does have a dyno.
But no matter. It's not real high on the priority list at this time.

BTW, I've noticed this loose brown wire before while poking around under the car, but lately it's just started nagging me. I thought perhaps it was a loose wire related to the STS system, as Aaron made some changes there, and who knows who condition Harwood had it when Aaron got it. But I figured since it was in the harness going to the passenger side oxygen sensor, maybe I should check to see what was going on.
Come to find out, that wasn't the only clipped wire there. There were several more tucked up inside that section of convoluted tubing. Best I can figure out, someone just clipped off that connector going to the oxygen sensor, and then apparently re-ran the wires. Possibly via a connector cut off of someone else's car. I can't tell where it goes to as it goes up topside on the engine, and I haven't tried to track it down yet. But in any event, someone cut off the connector for some reason and then rewired another one in place. Harwood was known for cutting off connectors from customers' cars as he needed them elsewhere, so he is the most likely suspect . But perhaps these wires are the reason for the oxygen sensor on that side acting goofy. I guess I'll see what happens during tuning if i don't get around to tracing the wires beforehand. It's not real easy working in there as it's tight quarters around the header pipes.

Hey Rich. I wouldn't doubt that may have come off my car. Harwood cut 5 connectors off mine while it was there collecting dust.

Got word last night from Lonnie's Performance that my fuel pump assembly is finished, so I guess I'll get that back next week. Still don't have an ETA on the new throttle body, though.

Been reading over this thread starting on when my car got towed to Aaron's shop on September 17, 2010. I'm up to February 7, 2011, and had to stop reading... A root canal without any novocaine couldn't be any more painful....
