I have have an 08 chevy 5.3 with a Comp Thumpr cam in it .
Part#54-600-11. 219/233 and 1.85 rockers.
I have the U7194. Can you diablosort tune for a "odd" camshaft? I am having engine codes p0300, p1174,p1175. Many are telling me that i need a "Real Tune" via a mail order. The truck runs good but i hate looking at a engine light all the time. I have sent my tune in to mike once to remove the p0300 but it still comes on. Any info would be helpful.

Thanks

219/233 @ .050?
really?

Interesting....it definitely needs tuning, but not email tuning, you really want to get it dialed in by a CMR tuner on a dyno.

yip, it is thier new thumpr line. it sounds like a dragster!!

Why did you put that big of a cam in for? RPM range is to high dont think the tuner will let you past 6000rpm! With the 1.85 rockers the aluminum construction and a roller bearing trunion which results in a 10% increase in valve lift over the stock 1.7 ratio rocker arms and gains of up to 12 HP over stock. So your lift on your cam is at a .608 int./.590exh. Comp has a chart that is best for
your app.

the dsp will let you raise rpm limit to 6600

yea it will raise it but you need to find the top hp an tq curve it may not be that high!! and you better buy a GOOD set of pushrods best being chromoly and springs for that puppy or , JMO but ive seen where some just get cam and rockers and everyone has regret it!!
