I didnt want to open a new thread, hope thats ok !

last week I installed my GEN3 and today I took the car to the dyno again. As you might have seen in my video thread I was able to realise a gain of about 6WHP compared to base line dyno with my cat-back exhaust system.

So I was very excited about how much the combination of exhaust and stillen intake will give me.

Unfortunately it looks like the intake actually steals me a lot of HP

we did like 4 runs in 5th gear (7AT) up to the vmax limiter and there was a significant loss compared to stock intake and CBE. However the curve still went up when the speed limiter hit so is it possible that the stillen AI moves the powerband way up the revs ?

Surprisingly when we tried to measure in 4th gear we made 2 runs with lots of wheel spin on the dyno even with a 260 pounds guy on the passenger seat. Last week with just the CBE dyno in 4th gear was no problem at all.

So it "looks" like we gained lots of torque and power from the G3 ... BUT ... after putting like 10 car batteries in the trunk plus the 2nd person in the car the dyno was actually able to measure without spin and again, we saw a lot less HP than we had before

is it possible that I need to reset my learned ecu values completely and drive the car for a couple of miles before the ECU can take advantage of the G3 ? I just cannot believe that this well recognized and prooven system will really cost me HP instead of gain ...

just to make clear, I drove the car for about 60 miles both in the city and on the autobahn and we did like 6 dyno runs in total - not enough time for ecu to recalibrate ?

please let me know cause it took quite some time for the install and of course cost quite some money and currently I'm really not happy at all !
