lost power, kickdown and performance after refueling

Hello everyone!

Mayday. I filled up my CL65 at Shell with a full tank (from 1/4) with 93 (allegedly ) and took off from the gas Station and immediately my car would behave as if if no longer had turbos..
-- no kick down
-- goes all the way to 7000 RPM if I let it and it's not shifting up... unless I start over and feather the pedal.
-- reverse struggles to move the car unless I give it more gas than usual
--- NO MISFIRE or anything like that.. VERY VERY VERY unresponsive....

I am completely lost. It drove perfectly right before I stopped at the Shell. It was perfect for weeks.. enough to give a Lambo a shock of its life (shhhh) thank you SPEEDRIVEN!!

Help!!

I suspected that yes. I remember LegitStreetCars showcasing it on one of their episodes. I can't remember the product he used.. I will look it up. Thanks!

or a bad gas pedal.. but the coincidence leans me towards water in gas. Found it! Heet gas treatment. https://amzn.to/3pBOXNf will try it tomorrow

I tried Heet and drove for 10 minutes.. and might have seen an improvement... (which turned out to be placebo). After scanning and rescanning faults, and suspecting I/C pump ( as suggested by many).. I opened the hood again and found... this torn hose. GO FIGURE!!

I still wonder how this happened....

ANOTHER MYSTERY

I can not find the equivalent of the Intercooler Pipe Hose that fits my 2005 CL65 AMG. The listed one A275-098-15-16 has "ETX 446 160 600" below the part number and is smaller by one inch than mine "with "VCD 446 160"under the part number... and is wider by a whole centimeter and therefore will reach both lips of the intercoolers.

Has anyone experienced this? The parts dept of Mercedes of Alexandria tells me the smaller pipe is the only one listed in the catalog. Help!! (See Pics)

*Is there some play in the intercooler boxes?
