Your limitation is the 4eat. A 4eat with a vf series turbo will not make 300 awhp.
Maybe try e85?

240whp seems kind of low for 22psi. Do mainline dynos read low or something?

Read the post right above you. An automatic will always show less power at the wheels than a manual.

Thanks for the replies guys. How much difference is the 4EAT vs MT in terms of power loss? 60whp sounds a lot. Unfortunately E85 not a option for me.

Did some looking up on Mainline dynos and apparently it has one of the lowest reading one, up to 8-12% lesser than Mustangs. But I suppose its accurate as my road dyno via Romraider yield similar result of 230whp/350Nm. Higher torque because I ran on gear 2. Not enough roads to go on gear 3.

I wouldn't doubt a 60whp drop through an auto especially a stock one. It also is dependent on how lose the converter is. I'm assuming this one is still a stock converter?

For some reason I think thats a little low. I have a similar set-up and I'm trying to get 300awhp on my stock 4eat as well. I'm near the 270-280 awhp on mine with about 290 awtq. I'll try to figure out some stuff and I'll get back to ya.

Edit: You have the EJ205 while I have the EJ255.

Just to put it in a better perspective. My manual stock usdm ej205 with close to the same set up, I had a fmic and couple other things. Made 244whp at 18psi at 5000" elevation on a dyno dynamics. Car also ran 12.6 @112mph at that power.

more info on 'VF22 Hybrid'

I had a VF22 on my 2.0 and made 360whp with e85. Curious to know what you mean by Hybrid.
