What happened on the 1-2 shift? Wideband went lean and boost dropped momentarily.

 

I was looking at that too... my guess was belt slip. Looks like it was slipping at the top of the gear causing it to drop boost, and then when it shifted and RPM dropped it caught back up, and boost jumped quickly. The comp was a split second behind it causing it to run lean for just a tick.

Thats the picture I painted in my head anyway...

 

Congrats man , truck is haulin *** !

No meth ??

 

It actually just tapped the rev limiter on the 1-2 that pass (and the one before). You will also notice the dip in fuel pressure at the same time. I am still trying to figure out the inconsistent boost since the swap. I previously though the boost was abnormally going up but after more analysis, I get better times and mph when the boost stays up so now I am thinking a boost leak somewhere. I was under the assumption with the new cam/heads the boost should be lower than the previous setup with the same pulley configuration.

 

Thanks, no meth yet. I have been checking out kits and will likely add one before next summer.

 

That's a really balsy tune up for 93 IMO.

 

Looks like it would have been good for at least 10.90s by the 1/8 ET & MPH. That's hauling *** for a full size truck.
