Stage 1 (DINANTRONICS Performance Tuner ONLY) Maximum Power on Competition Package equipped F8X M3/M4's: 532 HP, 504 lb-ft of torque.

The DinanTronics Power Module is the least invasive way of getting more power from your M3/M4. The Dinan tuner box plugs into the existing sockets on your engine computer(s). The original wiring harness plugs into the Dinan tuner box. There is no cutting or splicing into wires and the whole harness is completely reversible at any time. Dinan has shown a gain of 41hp and 49ft-lbs of torque with this system.

Because the DinanTronics module plugs directly into the engine computer, it can control the data from every sensor on the engine - not just the two or three that other piggyback-style modules use. Instead of only modifying a boost and RPM sensor, the Dinan power module sends a modified signal for fuel and ignition tables, target Lambda (AFR), exhaust temperature, knock sensors, and more. It has the ability to correct short term fuel trim and ignition timing errors so even as the boost increases through the whole RPM range the engine mapping remains where it should. Not only does it make a lot of peak power, but it's also a smooth and consistent power gain over the entire RPM band. The Dinan tuner module is the most sophisticated on the market and is the only one that is 50-state legal.

Installation is plug and play but requires access to the entire engine compartment. The engine computer(s) is part of the intake manifold so access is tight. The Dinan module is installed under the radiator support and the harness has to be run to each computer. Detailed instructions are included but professional installation is strongly advised if you're not used to working around your engine.

Note: This version of the DINANTRONICS Performance Tuner is ONLY compatible with M3/M4's equipped with the Competition Package. Compatibility with the Standard Package is available in a different kit.

Can’t read numbers

Color: 2926 Gold Stainless Steel/Gold Dial
I absolutely love these watches! They are built like a tank. They can take a lot of abuse and still keep great time. I originally was going to buy just one to replace my old watch. Ended up buying several of them. Great gifts. The watches are beautiful and elegant, and I feel like a thief when I buy them because the price is so low I think its a typo. I have gotten several compliments on them when I wear them. I have busted up concrete and cleared heavy terrain ,cleaning areas out, wipe then off and they look Like I just took them out of the box. The only thing, and it's not a big deal to me.But the glow in the dark arms don't last long. They even give you the tool to adjust the wristband. Who does that🤣 The Quality of these watches are phenomenal BUY ONE! You won't be disappointed.

Very handsome well-made watch comfortable to wear.
Color: 5885 Siver Stainless Steel/Blue Dial
Very handsome watch. At first glance, it resembles a Rolex. In two days I’ve gotten multiple compliments. Several have asked if it was a Rolex. That’s hardly what I was going for, in fact I had to look up Rolex watches to see what was being referenced. The watch fits very comfortably.

Good budget watch
Color: 2926 Silver Stainless Steel/Black Dial
Good watch for a budget, color is good. The pins holding the link together tend to wear out and fall out. Other than that it worked good.
