It was great, for about 20k. But not so much now. Shifting needs to be exact or chatter chatter. I got the lightweight flywheel as well
Dang, but held up for a good portion. Did you push it to the limits a lot? Or just here and there?

Haha my gf isn't to excited about it either. I'm Hoping to hit 400hp and not destroy the fx350 clutch. Unfortunately I feel that's going to be what holds my tune back.
Have you thought about the internals as well? Aren’t you scared of the engine not being able to keep up sooner or later? Also I’m assuming you went with the 2860r GEN 2

Just installed the PRL flex kit today. Pretty easy to install. I did my oil and trans fluid while I had the pan off.

The kit is testing well. Just did a start up and I can see the ethanol % is correct.

Awesome!! My prl flex fuel kit comes via FedEx today!! Im so excited to install it after work! Too bad I have to reflash my ecu with an OTS calibration because Derek from Tsp will be returning tomorrow and will delay my tsp stage 2 tune. Oh well. The patience game!
