On my last trip to the dyno I made 624rwhp and 529rwtq. Since my last tune I have added a Mamo RPS clutch and swapped from a Vavaram intake to a halltech mf103 with the Vette air scoop. Stay tuned I will post results later. Here is a picture of how my engine bay is looking these days and my first dyno graph. I will be on the same dyno today roughly same temperatures but more humidity.
What are you doing for the intake shroud since moving to the Halltech. I ask because Halltech told me I'd need a new uncut shroud when moving from a vararam to a Halltech due to the position of the maf.

Ok results are in not what we were expecting. My tuner and Tony feel the car is restricted somehow. Have to start looking into a couple things but it still makes great numbers. I picked up 5rwhp and 10rwtq at peak. There was more power under the curve though.
The swap to the Halltech, IMO, is a non difference, but I would have expected more from the Mamo'fied clutch. My guess is that the gain is actually there, but the correction for the additional humidity is the cause of what looks like a tiny gain. In any case, you still probably have among the higher N/A LS7s where you live!
What cam? Headers? Cats? Previous clutch? What rear tires? Results seem on pay with rotating mass reduction. Swap to 2-piece aluminum hat rotors on the rear axle and pick up another 8-10rwhp.
I hated the look of the vavaram. That’s why I switched
With some black couplers I think it looks pretty good. According to my testing it simply performs better for me so it's staying even if it is a touch uglier.

I have the standard Mamo package. I was on the stock clutch before. I also changed from the stock 325 run flats to 345 NT05R since last dyno pull. Cam is a 244/258 114+3
