Did you calibrate your JDM MAP sensor for the elevation you are at? I had the exact same issues. Ended up needing to re-scale my MAF since I had the ETS hard pipe intake and KN filter. Mucho better now...

The JDM Map is calibrated, I mean all you change is the elevation value based on what MrFred wrote in his thread.

As for the ETS intake pipe, the MAF scale hasn't been adjusted at all. What adjustments did you have to make Wicked E to your MAF table?

I will focus on doing the boost leak, the oem map sensor swap, and see what these two items result.

Thanks for everyone's input!

 

Spent a month re-scaling the MAF for the ETS intake. My tuner just finished and am now working on the full throttle stuff.

I would recommend reading the MAF Scaling thread and ask questions as much as you need to. That thread needs a major update but will show you what to do...

That's cool, thanks Wicked E!

 

Here to help if I can...

Any questions, just ask and I'll see if my tuner can answer them for you... I know that a LOT of attention was paid to the 2Byte Airflow numbers..,
