Cliff notes:

Torque loss of around 20 foot lbs from 3,700 to 4,000ish RPM. Highest gain under the curve looks to be around 35(!!) foot pounds at 5,000.

GT350 manifold starts pulling away at 5,100 for HP and by 6,000 RPM is up by about 35-40 HP.

The power figures do cross at 5,250 in this graph.

I kind of want the GT350 IM now.

The question is will the PP3 tune have the same issues as the PP2 tune that some have seen here?

Update on my PP2 install:

- I have the rev hang only on initial startup with (cold engine). Goes away once start driving.
- I do feel the abrupt deceleration once in a while when lifting off the throttle

- Fuel economy has improved during long haul.
- Before PP2 install - Raleigh, NC to D.C. = 23.4 MPG @75 MPH
- After PP2 install - Raleigh, NC to D.C. = 26.0 MPG @75 MPH

I just drove to SC from Florida. I was sitting at 26.3 MPG @ 85-90 MPH. Being able to be in 6th gear made the difference I think.

Does the car feel stronger after the IM upgrade? Seems like a lot of money for more HP only above 5K rpms.

From the graph the low end numbers look good. Increases in both torque and HP at 2k. Seems like thats the daily driver zone(at least for me when normal driving). More usable power down low in a good thing imho. Or is there something in that graph im missing?

Yes the car rips. It feels very comparable to stock under 5k, above that it pulls hard through 7700. Best mod for a N/A engine besides headers. FYI I am still running the stock intake.

It would be interesting to see an overlay of LMR's PP2 and PP3 results.

Feels like we had been waiting on this video forever.

That is some nice top end. I can almost justify the purchase

The Red and Blue lines do...

The grey lines do not.

The grey lines do not.

Any idea why the stock and pp2 TQ drops early? Looking like it's in the manifold change.

I did a dyno comparison on my own car with Lund tuning, under 6000rpm the cars power and torque was pretty much identical to how it was previously on the Lund tune, though the torque peaks were slightly lower but flatter. I did however go from 472HP upto 516HP with peak power around 7200rpm.

On the road the car feels stronger everywhere, it is simply nicer to drive which I am putting down to the flatter torque curve which also holds for much longer.

I also tested the two throttle bodies, the GT 350 one made around 10HP more beyond 6200rpm, otherwise below this they both made identical power and torque.

GT 350 TB is a touch snappier on response and gives the car a deeper sound, in cold weather on a cold start the 350 TB is ever so slightly touchy, but nothing to worry about, again on Lund tune, on Ford cal its probably fine.

Stock GT is a touch smoother but not as snappy and the car does not sound as deep, no problem with cold start at all on stock TB.

I have stuck with the GT 350 TB as its positives outweigh the negatives and being in the UK our climate is cooler, in hotter regions of US 350 TB all the way.

That is a really nice torque curve! I wouldn't worry too much about the puny loss on lower rpm range. What is amazing is the torque stays around and above 350 lbft from 3000 rpm to almost 7000 rpm vs 5500 rpm, and car keeps pulling till 7300 rpm. This is also on stock headers right? Headers should add another 10 lbft and 15 to 20 more whp. Add flex fuel tune with e85 on top of that and thats NA 500 hp of glory!!
