dyno letdown

[Darksun280]

How are you boosting 18 psi?

taking off the stock top mount jumps you like 2-3 psi

Those #s at crank are respectable. There is a bit more in there with a proper tune, but no worry it must drive nice!

My car runs stupid rich also. Seems like the mazdaspeed3 thing to do, unless you really start pushing it. I which SCT made s*** for this car. I put down 249.8whp/291wtq stock... but like as said before, dyno's are different.

Check some number of other cars dyno'd on that machine, then you get a good comparison. Whoever said 267whp = 325flywheel whp is WRONG.
