LET/Eurocharged Stage 1 Installed w/ Dyno!
Just wanted to discuss a recent upgrade as of early this week.
The vehicle is a 2003 E55. The vehicle seemed pretty healthy stock, going through a IC Pump replacement in 2007 with another Bosch unit.
Tuning was done at the Eurocharged shop location near Chicago. Thankfully, my frield was kind enough to drive the vehicle from Southeast MI for a Monday appointment.

First, a baseline dyno: 350.4hp
I was pretty disappointed with the baseline numbers. I heard the DynoDynamics dyno is a "heart-breaker" but didn't expect it to be a ball buster. Car felt fine, with no dead spots in acceleration, but the number alone was pretty alarming.
Tuning consisted of the following:
172mm pulley system
LET Heat Exchanger
CM30 Pump
Custom LET Tuning on Dyno
I'm happy to say the HP change is very satisfying
New Dyno after tuning: 422.9hp
Best part of this tune is the upper RPM power pickup - the Power curve does not drop off like stock setting. Highway pull is much better.
Overall, highly recommended!
I would like to take it to the track to get a good feeling of Trap Times. I'm curious with my initial baseline numbers if my vehicle has been running low in HP all this time and I'm now at factory e55 power. I'm thinking my reading was just low, as I've done multiple pulls stock against other vehicles, and outcomes are consistent with others on this board (stock e55 vs. stock 996T, E55 started pulling good end of 2nd gear into 3rd, about a car into start of 4th. A 570HP SC Mustang Cobra that pushed into high 11's was about 3/4 a car ahead from 40-140 mph).
Either way you put it, great gains from a Stage 1!!!
Thank you LET/Eurocharged! I can't wait to show my local shop that sells Kleemann and VRP.
The inputs/feedback from the board would be great!

Any plans on hitting the track?
from my friend- hardware upgrades yielded about 50hp without tune. I guess the multiple dyno runs for tuning potentially heat soaked the vehicle, so his gut/non-technical instinct is that the final numbers are conservative.
Only the track will tell!
