Headed to the dyno tomorrow to get some numbers. Bringing along a few mods to do some before/after pulls. If he still has my graph ill try and overlay with a built 347 ls1.
Car is an '11 P31. Mods in the pic
-ROW airboxes
-AFE filters
-Eurocharged V5 tune
I was able to pull all of the runs together and I think this will give a little better insight into the mods. The biggest gains were throughout the powerband, not peak numbers.
First graph is a back to back run STOCK vs ROW. You can see power really isnt gained until the 2nd half of the RPM band. If you exclude the dip on the baseline Peak gains were around 8whp and 6tq
Second graph is is the last baseline (heat in engine) vs ROW & Tuned. You can see there was a substantial amount of tq added in the lower RPM range. Max gains here are around 25whp & 30tq
Lastly is the same graph with STD correction if you're into that sort of thing.
I've got a 507 sedan and will be applying the Eurocharged V5 tune.
Procedure I'm planning to run is:
- Do up to 6 dyno runs stock to ensure stock ECU learning is optimised for Dyno
- Apply the tune
- Disconnect the battery and reconnect it (this is feedback from Eurocharged)
- Do up to 6 dyno runs with the tune
This should give us a decent comparison of the before and after.

Interesting, what was the reason for the battery disconnect?
I will wait to post up the graphs until I get home. The car was dynoed on a load bearing DynoJet 224xLC. The car was extremely consistent and the number went up with each mod.
One thing that is kind of bugging me is the speed limiter. After the Eurocharged v5 was applied, the car still appeared to be hitting the P31 (~174mph) speed limiter in 5th gear... because of that most of the pulls were done in 4th.
Cant wait to see the difference with the AFe filters and the Row Airboxes! Since I have already dyno'd with the v5 tune and need to decide if the filters and airboxes are worth investing in
