I'd typically agree with you here, but I've had great luck over the years, as well as countless others.

Walbro 450
e85
ID 2200's
700whp

To the OP, 06 and up was returnless, not an 05, so you don't have to redo everything.

The 525 for $199 over the 450 for $144. You think it will out perform the 450 by that much with that much more cost? The 450 seems to flow pretty well.

Overlaid the 450 and 450HP pump curves. Graph lines were taken from walbro/TIautomotive.

Average gain in flow is around 10gph or 35-40lph.
