LRP Flow works question
 

Flow works with a Reedy Sonic 4.5 550 in an SC10 4x4. Airtronics MX3fG radio

When I first installed the esc, I drove it without calibrating it to the radio. I was excited and curious... top speed was insane, but super hard to drive slow, as 5% on the throttle was more like 50%. Ran 1 pack like this, for kicks. Motor at 140, esc at 89. I then calibrate esc to tx, and turned "initial drive" setting down. Truck had normal low end feel, but now no top speed. Temps were 100/80. Got passed on the straight by a buddy's RTR sc10rs. Bumped "initial drive" back up, messed with EPA settings, and recalibrated, but no more top speed to be found.

What gives?

Do I need to add boost/turbo/timing for some reason? SXX/550 combo did not need this...

Bump! Nothing? Nobody has a suggestion? Any links to some FLOW knowledge?
