Default Thoughts? HP

04 2.0 Autobox custom block back exhuast, intake, timing mod, voltage stablizer what do you guys think im running from stock 150HP? ~170HP?

Also off topic How easy is it to remove our radio or is it a bitch to do? i'm sure this is probably in another tread but I didn't feel like searching through the hundreds of pages.

Have you remapped your fuel calibration for those mods? If so, then maybe the 170-175 would be realistic, not sure how much is really gained by just bolting parts on without calibrating the fuel system for the higher air-flow capability.

The radio is a snap. Ask icspot for a link or further info, but it's like pull the top of the console and a coupla' screws.

As for the rest: Exhaust, maybe 8hp. The CAI, maybe 3. Timing mod, doesn't really add any hp that I know of, just frees up some. I didn't notice any huge difference when I did mine. Say 1hp. The stabilizer=0.
150+8+3+1+0= 162 maybe... on a good day?

Well considering theres no real way to calabrate the mapping since mazda locks out the ECU. We have to stick with the "resetting" by the battery.

That doesn't change the base mapping.

A guy, screename Monzsta on another forum, figured out a long time ago that by resetting the sensor on the lower crankshaftyou can add timing to the engine while fooling the ECU into thinking nothing has changed.
Basically, loosen up the two 8mm headed bolts that hold the sensorin place, drop it down as far as it will go, and re-tighten the bolts... carefully!! The sensor housing is plastic and will crack if you're not careful about overtightening.
It takes about 15mins.
