How many HP is a midpipe worth after 2.76" pulley & tune? Is stocker choking me?

I just got a Billetflow Non-slip 2.76" & 100mm idler installed with a SCT XCalibrator tune at Sutton High Performance. Dyno numbers were 455 RWHP & 474 RWTQ with a VERY conservative tune (timing wise) & A/F (Max 11.8). Good peak numbers and huge gains under the curve compared to stock pulley. I am very happy with the numbers, but of course I want more.

How many HP am I leaving on the table with the stock midpipe? I am considering a Maggie catted-X if I am confident that I will get 10-15 HP.

How many HP is an Accufab worth at this point? Or should I just port the stock TB when I get the Steggy port? I really like the look of the Accufab, have they figured out the sticking throttle thing yet?

I am very happy with the job that Sutton did with the tune, it idles better than stock and runs like a raped ape , I am just looking for 475 ish at the wheels before I go to the Steggy port, any ideas or pointers out there for another 20 HP? Thanks in advance

I have "similar" mods with the addition of an MRT offroad H pipe and got the numbers in my sig. So I guess it is worth it!

Thanks guys, looks like I'll be orderin me one of them there x pipes soon
How about gains from an Accufab, 10rwhp maybe Maybe I'll just wait till the Steggy port and port the stocker, 5-6 hondo for a TB is a bit much at this point, when the blower & TB port is $500

With Single Blade TBs people have shown gains of 20rwhp, gains of 0rwhp, and losses of 10rwhp. The main idea behind getting a TB is to increase throttle response to give the car a snappier response. Most 500rwhp Eaton cars are running around with stock TBs. Although the aftermarket ones do look awesome :cool1:
