Frank responds very quickly to emails, for what it's worth.

Same RE brace as mine.

My experience was with an S54 Z3 M Coupe. Randy at Epic sourced the Bimmerworld box for me (out of stock at the time at Bimmerworld) before doing the tune. He was great to work with and I loved the tune. Our cars are different, I don't have a comparison dyno so cannot opine on power gain, but the sound, windows down, was glorious. I had Euro CSL headers, SS section 1 with cats, and SS mufflers. 280/272 cams. And a stroker crank. 355 rwhp. I think there was power to be gained by going to more aggressive headers.

That’s great news. I’ve considered swapping out my euro headers for more aggressive ones like you stated but I’m not sure if the swap is worth the money. I don’t have my car yet so I have some time to look into different tune options.

Josh at Severn Tuning has done a super job on my high boost M54. Highly recommended and a very honest and reliable contributor to this forumpokeybritches

I loved my Bimmerworld box but will say the TMS model would certainly be tempting at that price differential. IMO power gains are debatable given mine were in conjunction with Alpha-N and a built motor. Even if zero power gain the sound was worth the price.

Like some others, when looking at tunes I did not get a reply from TTFS. But that was 3 years ago. My experience with Epic was outstanding.

Randy has been great. I ended up buying some logging software that he recommended and I am going to use that to tweak the tune remotely. That said the base tune he gave me is running great... done two track days so far with it.

What is this logging software you speak of?

I’ll try TTFS once more, if I still don’t get a response I’ll consider Epic as my second option.

Ahh yes I keep forgetting about Josh. I’ll send him a DM on Instagram. Thanks Dave!

I have the Turner box on order, in fact it has shipped.

I’m also switching over to Josh at Severn. Sounds like a great guy to work with and knows his stuff. Randy was just too unreliable.

Have you received it yet Michael?

Received it yesterday and fitted it up. Mine required a little trimming to clear the shock tower due my motor being back 3.25”. Otherwise it fit well. Clearance to the torque rod is tight, and my motor sits low, but this could also be due to the motor sitting farther back. Most of the ports I’m not using since I have a dry sump. I also already have the IAT mounted forward of the radiator in the intake tube. For the brake booster blow off valve, I’m going to use a small fuel filter on it and not bother with adapting it to the port on the top of the intake.

On the NAM3 forum some were reporting it arriving broken due to poor packing. They must have listened as mine came packed in expanding foam in a big box. So no damage. Build quality looks great! There was one resin drip on one of the trumpets that I filed down to keep it smooth.

I also bought the silicone boots. These are nice and worth it. They use worm drive clamps, which I was using anyway, so be careful to allow clearance on cylinder 4 for the throttle rod.

I plan to run the car this Sunday at Road A. Not really expecting a power gain until I have Josh tune it, but do hope to hear the intake. Although my exhaust is pretty loud! Hell, the whole car is a cacophony of sound...
