Last I checked the 2nd cat was intact, in perfect condition actually, that was 3-4 months ago, no change in car behavior since then, so pulling the 1st is inevitable..

Exhaust/intake restriction, tired turbo or both. Considering how the BATs are climbing despite the relatively small load I'd incline towards exhaust restriction, things are getting hot down there. Gonna speak with my mechanic to check out the cat/turbo. Thanks for all the info, very much appreciated!

Thanks for the info. As requested, I've made another log and here are the results, 4th gear pull.

Ok, so I've flashed the Base 93US/98EU Octane map. Here are the results. I also used Torque for virtual dyno and got 175whp there.. Car feels way better than before though, somewhat running smoothly.

If everything is mechanically ok with the car then definitely yes, retunning with versatuner should theoretically fix this low power issue.

Thanks again very much for your answer, I'll try the most stockish tune available and I'll share the results!

The turbo on your car can do a lot more. Also, judging by the values in this log (which looks pretty weird from a formatting standpoint) you don't seem to have any problem with boost or vacuum leaks either. I'd say it's the tune. Can you share your tune, assuming it was tuned with versatuner? Thank...

Hi. I have a 2006 mazdaspeed6/mps with rebuilt engine, forged pistons/rods, and supposedly remapped for more power, other modifications of the car is a JBR short ram intake, HPFP upgrade and an OCC. I went to a dyno recently and got very bad results (150 whp :( ). I have been to several mechanics si...
