Major loss of horsepower in 05 cl65....
2005 cl65
eurcharged tuned
intake
full exhaust
trunk tank/pump
car made 660rwhp on dyno with 100 octane
ran 10.9@127
Car has been running like **** for a while and want to get sorted out Ran the car lastnight via dragy app
and trapped 117mph .Been to two Independent shops with no luck. car has no CEL or stored codes and runs fine until you get on it. struggles to get over 100mph.
checked all vacuum lines and sensors all appear to be good. compression check ok, fresh spark plugs and boost solenoid. I even sent ecu back to jerry and he said all was good.
ive logged iat's and they're under 140deg on all runs. Also have logged boost and hits 20psi@ full throttle and tapers off to 15psi. boost seems off as I remember years ago seeing about 25psi on hit and tapering to ,18. Not sure where else to check or what could possibly be wrong. any and all help greatly appreciated.

my boost on a CL600 with stock turbos

I hit 9.7@127 before the Methanol already
after methanol 34 psi
gonna run a new measurement these days when the weather allows it
you need at least better radiator, pusher fans, 2 pierburg pumps, a kleeman tune, methanol injection, suspension tune and a LSD differential of course
my car is so fast now , it behaves as a 200 pounds go-kart
