Strapping the truck (and the Chevelle) back down tomorrow.

Initially, it pulled it WAY down. As I brought in more duration, it stopped cutting the fuel so much.

First pull, it brought the commanded down into the 70's. As I brought the duration in, it only dropped to the 120's. It was pushing plenty of fuel, I had fuel to spare.

There are a couple areas in the tables that needed to be tweaked to keep the fuel from dropping, but you could see it in the logs, epsecially when comparing it to portions of the dyno graph.

The fuel is there, you just can't expect it to smack ya and say, "Here I am".

I've said to a lot of folks with other tuners.....DON'T TUNE ON THE STREET! You'll just piss yourself off and end up with a mediocre tune.

Here's a few clips looking back at the exhaust on the first few pulls.

The very first one was with the original tables; you could see it taper off real fast.

The second two were the first pulls on the new tables. These were only in the mid 600 range.

You'll see it pull back fuel in the top end until we started teaking th new tables and bringing in some duration.

For everyone else that's just a plain horsepower junkie, heres the Chevelle on the rollers.

We pulled it off after this as the intercooler is presenting a HUGE restriction. On the inlet side we were pushing 30 psi, but only 12 psi was making it across to the outlet side. That's a pressure drop of 18 psi when it should be 1 - 1.5 MAX.

So, we'll either need to get another intercooler made than can handle the CFM flow or we'll run a straight pipe across and use a meth kit to cool it.

This pull was approx 745 hp with 12 psi making it to the engine.

Oh yeah!

All this week has been working on the driveability and I now have it giving great response and almost no smoke during daily driving unless I really get down on it.
