Why does kleemann say stock injectors are fine ?
I recently purchased a set of Bosch ev14 550 injectors from e55amgrocket (thanks btw) for the future when my car is making around 500 to the wheels.
This is what I have been told by a lot of members here that it's kinda the gold standard to upgrade injectors when ur making around 500 to the wheels.
When I was inquiring about getting them installed at a highly recommended shop that happens to be a authorized kleemann dealer they thought I was crazy and said he had done numerous E 55s without every upgrading the injectors with zero problems whats up with that.....
I installed my 185 pulley and Eurocharged 550 injectors for my own peace of mind. I also have a friend with a 180 pully and tune and his stock injectors run static at 5600 rpms, so that should say something. He now has a fuel rail and injectors. Again peace of mind goes along way.
My 02!

Just saying EC has done a lot more custom tuning to get more files down for
Cars with bigger injectors and more mods

All its going to take for that shop to change there mind is flipping the cost of one engine failure to a leaned out #8 cyl.




Also managed 191mph in ~1.5-1.7 mile vmax day...
Stock injectors... and fuel rail.
Fastest E55 on the day ... all bigger pulley cars were slower.
Its interesting how different tunes and methods reach very solid performance levels...

Iv seen a 168 pulley k tune car run a 11.2 on pump and full weight and kleemann had a custom tune on it.
I have about 30-35,000 miles on my car and its well north of 500whp
I dont see anyone making my power with a 178 pulley and a ec tune and i only have kleemann headers and front catts and the rest of the exh is bone stock.
My car also runs smooth and feels 100% stock and just pulls clean all the way to redline.no fuss and iv been there and done that with retunes but kleemann did it right and have there tunes perfected with there first flash.
There k4 file is worth it and i wouldnt run another tune even if you gave me 5 grand with it
check out this car built at fabspeed,all it had was a k2 setup.168 pulley and kleemann headers and broke 520whp

I asked for more power and they had to ask there engineer that cant speak a word of english and he came back and said your car will knock and pull timing if we add anymore and that Im at the very limit that they will go.
I actually told them I want to lower my boost to a 168 because I cant use the power on the street and love how people that have never even been in a k car think they are conservative.
I dont remember what my first gear feels like as its been over 2 years since I went wot in first with traction and that was with a EC tune btw!!!

If you look the word up you will understand that what I meant is "tending to be moderate or cautious: a conservative estimate "
It was meant as a safety point not with limits or saying that they can't be more aggressive.
No problems with kleemann tune after many hard miles (about 2 years if not more has the car been running kleemann tuning). Car is pretty much "heavily" modified as most would consider here. If not more modified than most E55s you come in contact with on this forum.
