Not sure what is up with the car, but I swapped in some 36lb injectors(had 30's) and had Bryan at pcmforless change it for the 36's and up my shift points and rev limiter. Now the car ran 11.78 at 115.6 on the drag radials with shifting at ~5900 last weekend with the 30lb injectors and the last tune. On the new tune and new injectors it feels a lot slower. Then when I put it on the dyno on Saturday, it only did 368rwhp/388rwtq but it flatlined at 5400 to 6200, then at 6200 it dropped off bad to 6600 where we shut down. The a/f was 11.5 to 12.2 the entire run so I know it's rich, but would that cause it to flatline this bad? I already sold the 30lb injectors so I can't put them back in to dyno it to see how it runs. Any ideas what is wrong? I'm waiting on a new tune from Bryan to see how much better it runs.

Here's the chart...

Nothing to worry about.

Retuning will help gain some more HP. What kind of torque converter/transmission are you running?
Flat line doesn't necessarily mean bad. If you're looking at the graph it shows that you get a fairly constant power and torque supply throughout the whole rpm range, whereas with other cams, they usually start low and work their way up. This is a nice cam.

FWIW, Joe O cams don't always put out AMAZING numbers on the dyno, but they kick *** at the track.

 

3600 yank and built 4l60e. I've dyno'd with the yank before with my old setup and it pulled to 6400 with the baby cam. I'm just trying to figure out why it stops pulling at 5400, because that cam should keep pulling to 6600+. Ion, I'm sending you a PM.
