Tousley Ford. It was a little over $500 shipped.

Thats nice looks like pretty consistent 7rwhp across most of the RPM range, I say well worth the money

Good observation. The power under the curve was significant. Average hp went from 373 to 391 for an increase of 17. Average torque went from 441 to 457 for an increase of 16. Max boost dropped .4 and average boost went down .2.

The second dyno sheet shows the new tb with two different pulleys. The motor is making almost identical numbers with the frpp tb and a 3.375" pulley as it was with the stock tb and a 3.250" pulley. All with about 1.5 lbs. less boost.

Those are nice gains. With all the negative posts on this forum in regards to aftermarket tb, most people only focus on peak hp numbers, which i agree, is usually minimal. But mid-range power and better throttle response is where significant gains can be had. And unless all you do is drag race, most of your day to day driving is spent in the middle rpms. Driving around town, im usually shifting between 3 and 4.5 rpms. And regardless what the tb manufactures claim, in order for it to work right , it must be tuned. Sure, you can bolt one on without a tune, but you're car will probably run like crap, and most likely lose power. I've had one for years, had it tuned and it works great.

I was thinking about picking one of those up. How is the throttle response?

It's just like the stock tb, so far. I haven't had a chance to really test it in a real world wot situation yet.

The next Friday test and tune is a few weeks away for me.

Be interesting to see what kind of difference it makes at the track. Keep us posted.
