Yeah I guess I always go the impression from Ted that he was doing some amount of testing on the dyno, but he wouldn't put up the actual numbers. Only a range of percent of increase. Which I guess makes sense from a business point of view, if you put up dyno numbers you are opening yourself up to every idiot with a truck that runs like crap trying to say your product doesn't run as advertised.

I spent a few years tuning a Wrx and I don't remember any of the mod companies I dealt with putting up real dyno results. They would just make a vague dyno-looking chart without any numbers (totally worthless) and really just say what "stage" you should be at to run that piece of gear. Maybe that has changed but it was Cobb and Turbo XS, pretty big names in the game, and they seemed to have no interest in provided a real chart to the public.

All in all with a 22RE cam, looking at those charts you posted it is apparent that mostly what is happening is shifting the power band one way or another. Peak torque and HP never vary by that much. I would certainly question anyone who can feel the difference between couple of ft/lbs or HP. It looks like the 252 should be a touch better than the 261. And I cant even really compare from when I owned one because now I am running a RV head with oversized valves. If Ted is right and that head provides 6-10% increase than that is far more than a cam change can do. I am a believer in that head, that is for sure :) I can't really see throwing $230 at the 252 to maybe gain 2 ft/lbs, haha.

Did engnbldr have any response to the lobes being off-center? Can't see that causing your engine issues, but it might speak to some QC issues in that production run.
