I was recently traveling with my brother in his RV which is powered by a 330hp Cummins 8. 3 ISC engine. He asked me what was the maximum boost I got with my 5. 9 Cummins. After I told him he said he was not getting more than 5 or 6 psi. That seemed low to me but I said I would try to find some first hand info from the TDR forums.
Are there any ISC owners out there who can give me some numbers to relay to my brother?
Thanks
