Do I need a retune?

[THAITED]

I plan on adding 18% OD crank pulley and bleed of the boost at 16-1/2 psi with Boost Limiter Valve (BLV). I'm looking for more low end torque.

I have a drawthrough MAF. I contacted 928 motorsports where I bought it from, the guy told me"no" with no further deatils.

He said the boost would come on sooner at 2500 rpm not 3500 rpm. I don't want to run lean on the low and mid RPM. Do you think I need a retune.

Thank you

I wouldn't think you're going to be able to run that set up with a draw through MAF. You're going to be venting metered air. That's going to mess with the ECU.

That being said how often are you punching it at 2500rpm anyway?
