There is another that is trying out a stand alone ECU for the 4.9, I am following him to see how he does. A lot of these aftermarket ECU's have come a long way for sure.

I still have tuning to do and need bigger injectors, but it can be done quiet easily. Just dump the factory stuff, go ls coils and mount a 36-1 wheel up front with hall sensor.
Supercharger is optional

Speeduino, costs $150 and has four channel ignition/ four channel fuel. And you can tune via Bluetooth!

My friend has TunerCat and is gonna grab the 4.9 file. He said it's only $23 for it so no issues tuning it. Hope to be back at the dyno within 2 weeks. This is a getrag 5 speed car. We has added the 12v to the PS wire on the ECM. Had sold the car in 2014 and bought it back about 2 years ago.
I have a lugnut that just spins so I can't put on stock wheels on right now to measure it's true(ish) power but 200/300 with 51 lbs wheels is pretty good. These tires are running 040 treadwear and the traction is amazing.
you can see it in action here with 56 lbs 17x10 wheels with 315/35R17 100 treadwear tires...in my last race I hit a bump in turn 3 and my rear end bounced hard thanks to my 500# springs...:

Once this is fixed 200rwhp and 300ft*lbs should be possible. I am also running 17x9 wheels now which are 2 lbs heavier than the 18x8.5's I was running before. An old dyno when I was pig rich had me at 175/275 so with not tune I picked up 12hp just switching to E85...

So, did you just put E-85 in the tank without any tunning?

What injectors are you running and at what pressure.

I used some Ford Thunderbird 4.6 DOHC injectors. Stock pressure but they flow more because Ford rates them differently... Bought them along with a custom made fuel rail to mount them. Hasn't failed me yet!
