Cams and stock maf
I am currently running a t25 setup and want to install BC stage 2 camshafts. Am I pushing it too close with the stock MAF with 12lbs of boost? Fuel setup is 3bar piloted with a calum basic 370cc program.

No Chris, you will be fine... the car wont make more than that maf can handle at 12 psi....

With the cams it should be close to that 250whp mark. I just don't know how close is too close.

290whp is the limit on the DE MAF, so you should be fine.

That's only when it's bored to 54mm though.

Really you might be all right and you might not. It all really depends on other factors like compression ratio and other supporting mods. The only sure way to tell is using a TechTom or some other datalogging program to monitor MAF voltage and Injector duty cycle. I've had my S4's sitting in my attic for months because I wanted to wait until I upgraded my MAF/Injectors/ECU. I just did the wiring for the MAF last night, today I'll be hooking up the new ecu and starting with the cams.

I have found a place that sells the cmx-100 n2 for $200. My searching endeavors have only led me to one site. Any other sites to compare with?

Edit:Not even sure they are in stock.

If you think your coming close.. just turn down the boost until you upgrade your MAF

I get some serious spiking for some reason. Bluebird turbo with 7lb wastegate and it spikes to 12 then falls back down. Thats why I was wondering if it was safe.

Edit: Aem wideband on the way to solve my worries.
