I've been on 4 here in the city. All operated by same people and my tuner worked at or he's owned all 4. All have read the same. That's the beauty of dynojet. All use the same algorithm and everyone here uses same correction factors.

Added latest results to the OP. 347/276. Has new wavetrac diff, Z1 bushings, collars, diff cover, and 18" wheels instead of 19". Temps were the same.

I'm putting this out here because this setup works people. The drivetrain is more efficient with the new differential and clutch/flywheel. The intake side is port matched from filter to throttle body, the upper, and lower manifold. The Z1 Headers are super smooth with a proper merge collector. The Fast Intentions exhaust welds and sands their flanges from the inside. It's super smooth all the way through. Nothing is sized inappropriately. There's no extra large TB's or 3" intakes. I just added Z1's filters and Fast Intentions crash bar. The crash bar gave me clearance for the filters, oil cooler, and a much larger opening to pull air from.

With a bad tune, I was only making 315whp. After Martin fixed the issue, it jumped to 326. Then to 342 with the new clutch when it wasn't balls hot and humid outside. And finally 346 in the same conditions with the new diff and gears.

Ecutek allowed me to fix SRM and the speedo. Maybe she has 350whp in her if the humidity drops under 50%.

I think if you dyno on the coldest day of our central florida winter, you will hit 350.

I love how your car went from "Something is wrong and it is worrisome" to making a ton of NA power. =)

I assume you've probably put a few miles on it since the 4.08's. What's your impression of the lower gearing?

I wonder if you where to add a water/meth injection kit just to lower the intake temps if it would make a difference.

I know of another product that definitely would put it past 400whp; if injected....

I'm having my pinion adjusted right now. Hopefully Dyno later today. I haven't drove it much as I recognized some symptoms that needed checked out before it caused damage

Diff needs adjustment. Pinion is too deep in the ring gear. Luckily there wasn't any damage. I won't have the car back for a few days
