    Dyno Results......

    I went and got the truck dynoed today. Results to not to good. (209 hp, 210 trq, they are sopost to send me the file, the printer was down) They said they are almost sure the trans is slipping. That is probly why i felt like i needed more power, because it didnt seem to be all that much faster than the bolt-on 4.3(well recently, at 1st it pulled strong). Allen dynoed the stock 5.3 on the 100hp buget gain thread and it put down 224hp(not sure what kind of dyno though). This was a dynodynamics pull. I know it would be a little higher on a dynojet. What do yall think?

    maybe the drop in curve has something to do with it?

    Someone steal your turbocharger? Sounds like you have a mega-low compression engine. What cylinder heads are you running, 317s?
