Stage 2 (DINANTRONICS Performance Tuner in conjunction with Dinan Intake and Exhaust) Maximum Power: 381 HP, 403 lb-ft of torque.

The DINANTRONICS Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negating or voiding your new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It is also the only tuning device emissions legal in all 50 states. The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied package.

The DINANTRONICS Performance Tuner uniquely has the capability to adjust target Lambda, correct short term trim as well as ignition timing errors induced by raising boost pressure. This enables Dinan calibration engineers to optimize air/fuel mixture and ignition timing at elevated boost pressure throughout the entire gamut of engine RPM and engine load. Additionally, the ability to correct short term trim corrections (the difference between target and scheduled fuel mixture) remain within OEM specifications. This minimizes knock sensor activity, which in turn means smooth engine performance, catalyst protection and power increase, while this is also required to make the car emissions legal. Dinan engineers have worked for two years on the DINANTRONICS Performance Tuner in efforts to provide BMW enthusiasts with Performance without Sacrifice.

Perhaps best of all, the unit automatically detects which engine it is installed upon and loads the appropriate mapping. Effectively making a single unit compatible with an extremely wide range of applications making switching to a new vehicle, sharing with another, or selling the unit a breeze.

Note: This kit is currently NOT for cars equipped with BMW M-Performance software (MPPK). For MPPK equipped cars there is a separate part number. This version of the DINANTRONICS Performance Tuner is ONLY compatible with vehicles equipped with a mechanical wastegate.

Best soothing chew toy for puppies yet!
Fantastic products!! Got these for my son’s 10 wk old chocolate lab puppy. He immediately started chewing on one and continued for close to an hour. I wish I had tried these with each of my own labs when they were pups (we’ve had 5 over the past 20 years). Inexpensive and an easy way to keep a determined chewer occupied without food/treats. I highly recommend for a heavy chewing breed like Labradors!!

Junk
The star didn't last 24 hours with my 5 month old Frenchie. She chewed a piece off the blue rubber star and I think she ingested it bc I can't find it. Hoping and praying she doesn't get sick from ingesting it. I won't be giving her anymore of these.

Nice toy for puppy to chew
Nice puppy toy to teeth on but I would have given it 5 star if only it had some crinkle or squeak to it!

Short term fun ending in stuffing everywhere
My dog loved the toys, from the start he grabbed them and ran off to play. However the quality just doesn't hold up to a 7 month old 42 pound mixed doggie. The star toy broke immediately and I had to throw bits of the plastic away. He did enjoy ripping the other toys and pulling out all the stuffing. I did not enjoy picking it all up on the yard. For the price it was OK, but didn't last long and needs supervision for the inevitable destruction. At least he enjoyed them while they lasted, which is why they got 3 stars instead of 2.
