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?

Yup after i get the prl flex fuel kit, im getting the 27Won Turbo upgrade

i'm 23.. so i pushed it. i also daily it. 44k right now. i was running a custom tune for 50/50 water/meth injection on this clutch. i was making about 250hp, 320tq on a mustang dyno.

yup the gtx2860r. and no on the internals, still stock there. a little scared but i'm seeing others pushing it on the stock block. MAPerormance being one of them.

I run the PRL kit with the TSP Stage 2 tune and it feels great. Very easy install and great increase in power.

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!
