ISX egr tuneup vs X15 egr tuneup

[marek4792]

I posted part numbers on another thread but I'll post them here as well, 288k is quite abit late, no more than 150k miles on sensors and while you have everything out of the way I would run the overhead too because waiting til 500k you might be replacing the camshaft. Post pics of the imap when you pull it I'm interested to see how it looks.
My engine is a Performance series so this may or may not be the right numbers for your X15
Egr temp #5461596
Egr differential #4358939
Exhaust pressure #4928594
Imap #2897334 <------ double check this number quickserve is not showing it for the X15
