Cammed lq4 not making power? 2004 lq4 with 243 heads shaved 7 thou, custom cam 222" 224" 561-568 112 Lsa and full exhaust short tubes and 3 inch piping. Stock TB and intake manifold. CAI. On 91 octane fuel. Through a built and stalled 4l70e I got it dyno tuned the other day on a mustang dyno. (Shop is about 60 feet above sea level) it only made a recorded 315 rwhp and 325 rwtq. The tuner said mustang dyno usually read lower than others which I expected, he also said his will read roughly 15% less than a dynojet or other brand of dyno. Which he said would translate to roughly 365rwhp and 385 rwtq. The question I have is that I see videos and dyno sheets of stock 5.3s putting down 245 rwhp and 260rwtq on mustang dynos. Am I only really gaining 70rwhp? Does anyone think there's more to gain through tuning? And or my intake having some restrictions somewhere? Thanks in advance

It seems low, but it's just a number. How does it feel? Whats the fastest car you have been in? And how does it feel compared to that? The track is the real dyno. It will tell you how it runs, and approx how much HP its making. Do you know of any other cars that have been on that dyno? If so, what were they and what did they dyno?
Was the cam degreed in? Do you have HP Tuners? Do you have any idea where the map reading was at WOT?

70 Horsepower from a cam, a little bump in compression, and a cold air intake and, and you are disappointed with this? I think you are in pretty good shape. If the mixture is on and you're timing isn't low, I'd be looking into the 1/4 mile numbers and how the car feels on the street.
Also, consider that these numbers are going to translate to 400+ at the crank... so that's not terrible.
