Our C 250 CGI was still a bit sluggish compared to our C200 CGI with Torque 500 RPM after the C200 round Town. "The Atomic Boost Controller" smartened the immediate Throttle response quite a bit. It is installed "after" the Factory Electronic Controller in the Vacuum Line and lets the Turbo Produce about 3/4 lbs more Max Boost.
Also Boosts Torque. which comes in stronger from around 1500 RPM.Car is much more derivable. Though it is but a band Aid on the Factory setup for Torque higher in the Rev Range. That can't be altered.:D
Too much adjustment on the Controller triggers Limp Mode... ask me how I know !

Good results keep coming... On a run with 100 to 110 KPH Motorway Speeds today I averaged 7 litres/100K. down from 8.3 on the same conditions. Similar Traffic and Temperature etc. Turbo now spools up from 1500RPM by holding the Waste Gate closed longer .. It is linear up to 6000RPM. Transmission in the S position for later shifts to prevent the Engine lugging at low Revs, below 2000 revs .It will now pull strongly from 1500RPM, if I let it, in the D position.
The Engine doesn't sound or feel stressed but the result is additional load on the Big End bearings from the added Boost low down.
This Manual Boost Controller can be added to any Turbo as most have a very conservative set up. But be careful not to add too much Boost... disaster.:cool:
