Not necessarily true. The .48 will spool faster, which is perhaps what some folks are after, ie. autoX, drifting, gymkhana. Plus, a comparitively larger A/R turbine can be detrimental when you're running a smaller boost setup anyway. In this case, it's better to get into the boost quicker and produce a broader, flatter torque curve. Also, the type of manifold used can have a much more pronounced effect on the performance differences between varying turbine A/R sizes.

You're recommending a specific turbine A/R...and then later, the turbo specs you recommend just happen to match the turbo you have for sale. Interesting.

People have been running FMUs for a long time now...longer than a lot of the people on this forum have been alive. It's true that you can blow a motor with an FMU. But you can blow a motor running an SAFC just as easily. For a low boost setup, ie 7 PSI max, where you don't have to worry about major timing adjustments, a properly sized FMU works very well. I've run an FMU and datalogged hours and hours of AFR, RPMS, boost, and injector duty to say that you can run an FMU just fine without risk of blowing a motor. It's not ideal for a track setup, but then again alot of people are only after a little boost for their daily driver and an FMU makes sense in this case.
