Hi, everyone happy to be apart of this forum. I have a question. I have a 2002 C230 sport coupe 2.3 It has a Carlsson pulley kit, chip tuned by Upsolute Chip Tuning and a K&N open intake filter. I just put on a boost guage on and at max boost it reads about 6-7 psi. I was told I should be getting around 10-11 psi. What do you think is wrong and I should check.
Thanks

 

Thanks for the info. I also heard that using a K&N oiled filter may cause problems with the mass flow. The oil gets on the wires. Would this cause my boosting problems?
Thanks

 

Thanks again. So if I have a cold air intake system what air cleaner woul you say is the best?
