Does stock ECU adjust to Crawford Billet Power Blocks?
 

Deciding on getting a CBPB but I'm wondering if the stock ECU is going to adjust anybody know of this happening? For the power to stay do I have to tune? Thanks in advance.

No, save your money.


I assume that you already have a header, full exhaust, intake and custom dyno tune to even be considering these.

There are a number of threads on this already. I have not read aboutthe ECU reducing the power over time.

They'll give you a bigger increase untuned than they will tuned. That is, they're better value on stock tune. I had to pull timing from my normal map to run intake runners, but that's on our shitty fuel.

affects to AFR?

No, be more concerned with knock
