Utterly maxed we've seen a X hit 400tq on stock turbo on your dyno but less than 400whp. I assume you do not have a tubular or cams. It might be a good exercise for you to stay on stock turbo until you really max things out. There are different ways to do that. Kracka is focusing on FMIC/piping/TB instead of cams/exhaust mani right now.

I wish I'd run my car when I was 360tq/340hp at DB. I suspect it would be in that 400/390 ballpark.

Yup, I've been sticking to mods that basically have no drawback. After my IX I decided to shy away from cams and a lightweight flywheel on my X. So far my fairly basic mods have been good for 360whp/380wtq (93 octane pump gas) on Cobb's Mustang dyno.

-AFE/Perrin intake
-MAP o2 elim dp/ETS testpipe/Cobb catback
-ported/coated stock exhaust manifold
-ported stock IM/TB
-Walbro 255 fuel pump
-Grimspeed 3-port BCS
-MAP FMIC w/Nisei UICP (stock LICP)

The only other things I'm considering at this point are a set of larger fuel injectors and a mild upgrade stockframe turbo (something the size of a FP Green or BBX-Lite).

Back on topic: Nice progress, Chris! I'm looking forward to seeing more product details/pictures of your testpipe and catback.
