what RPM does you LLY start to build boost?

[turbo lcc]

Mine starts to make boost about 1900-2000rpms.. I just wanted to see if that sounded right to everyone (with a 65hp predator tune in)

It depends on the load, in any turbo'd engine. You may not see much boost below 1900 when empty in the lower gears. Put a load on it and the boost will come in sooner. It will also be sooner if the torque converter is locked, as the torque converter doesn't let the engine load up at lower RPM's.

Like DmaxMaverick said, it is load dependent.

I see boost stabilize to 8-12 psi at 1500 RPM full pedal in holding mode at the beginning of a dyno run.
