    depending on if they've got the cams installed properly and phaser kit it should make up to 400whp... 350whp is what a bolt on R/T usually makes...

    Well honestly man just looking at the tune you sent, it looks like you are tuning this cam with ANN. i would switch to SD, that's how i tune for bigger cams.

    looking at how the trans side is adjusted it seems as if you're doing dyno pulls in first gear, there is no way your whp numbers will be accurate in a 3.6 to 1 gear, it will lower power #s significantly.

    Also I would change the trans tune A LOT.. as well as raise timing.. it should be pulling around 19 to 21* easily.
