well my outcome with H&S Chip+BMC Filter+RENNtech pulley= 40-43HP and 50-53 ft.lbs of TQ (at the wheels values), with no headers and IC upgrade yet.

US$ 1,290 with shipping to Germany and return.
BMC filters:
US$ 150 (the two filters and shipping from Italy).
RENNtech pulleys
US$ 1,995 (pulleys and 2 RENNtech filters).
Total: $ 3,435, like the same that the RENNtech kit(ECU+Pulleys)
I have not installed the RENNtech filters I am using the BMC, and I have not installed the SL55 Y-Pipe either ($85+tax).
Summaring, for me the best $/hp is go with H&S+BMC= $1,444, and even more if you are at sea level, 0 fts elevation. Or go just with ODPS EVO's kit that is good too $1,690.
Next, either way get the RENNtech pulleys, as I did, or simply buy the RENNtech kit(ECU+Pulleys) as a first move $3,495.

PierreC32: Good info.
I do have one concern. Your last run, 007 - blue one, looks like the engine has detonation/missfire. At 5300 rpm it is pretty severe - about 20 ft.lbs. drop.
Looks like you do not have enough octane for the timing curve H&S is running. The wavy line is due to knock sensor pulling timing out. Look how smooth run 003 is.

One think that I am going to try to do is change the air filters, for the RENNtech ones, or even the stock one; because perhaps, I will get less pulling timing out with less air.....what do you think Vadim?

PierreC32: Yes, you are detonating. As you can see the new graph (blue) is significantly richer - mid11s vs. mid12s. DME is trying richer mixture to prevent detonation.
See if you can locate Unocal 76 station in CO. Some sell 100 octane. Try runing half 91 and half 100 for a about a 100 miles and redyno again. You could see as much as 20HP. Good Luck!

Pierre,
Until you are able to fix your a/f ratio, you should baby your engine. You need to find a permanent solution to your engine detonating. In a short while, semi-hard driving can leave permanent effects on your engine. Not to toot our own horn, but this is why we design our mods to run safely on 91 octane...
Good luck!
