I have a TD5 with an inside TD5 stage 2 map and its hitting 670 in the MAF readings.
Car seems like its cutting the fuel.
I'm about to try a stage 3 and sure ill need something to confuse he ecu.
Ps the stage 2 from inside has been awesome so far.
Totally recommend it as I feel like my car is totally different since re mapping.

I have a irb box,

Ian can be very hard to get a hold of.... i have the adjustable one you will a nano or similar to set it up.

If its cutting the fuel it will more then likely be overboost, do you have normal boost box fitted?

How much boost are you running and on what turbo?

and any airbox or intake mods done ?

I have a nanocom evolution and am not getting any overboost errors in the ecu. Boost is getting up to 1.29 and has gotten up to 1.31-1.33 a couple of times.
MAF regularly gets up to 670 and that seems when it cuts power.

Seems quite high maf readings for only 18-19psi is it genuine maf?

when the maf goes out of range it will drop off, readings should go back to 0 or 4.4 when it goes out of range.

is this on stock turbo?

Yes stock garret Turbo as far as I can tell.
I have a larger inter cooler but it was getting those readings prior to inter cooler.
I believe the Maf is original but not 100% sure. What's the best way to check?

Forgot to mention I have a Safari Snorkel which I guess acts as an air ram also.

Anyone else get high 600 readings on MAF with a remapped ECU?
Anyone else recommend the IRB dual limiter?

No it doesn't

No worries Tombie.

Any ideas?
