JB4

Mpower77i · 09-03-2011, 10:10 AM

Picked up a brand new JB4 the other day and love the power. Problem is that since day 2, my oil light has been on, showing that my oil level dropped. Im guessing its because of the added heat associated with more boost. So my question is, which map would run less hot,1 or 5?

Thanks

Map 5 can run hotter or colder depending on conditions. There is no real "longevity" savings, just run Map 1 IMO since you have 93 octane in DC.

And top off that oil ASAP.

Forgot to mention that my only mods are a JB4, DCI and 93 octane

With your mods map 1 is fine ,I would run map 5 if you want to try to maximize your cars full potential ..

No tune for engine longevity

But to answer your question, Map 1 as Myst suggested.
