i went from a 48v to a 58v (not flashed) and noticed better cold starts. A little more pep. But i do get the P0611 code for ficm performance.

I went ahead and got the 58 with no tune and have had better starts and more pep as-well, but Ive never popped a code.



SO out of curiosity what does p0611 mean/cause

I THINK 58v is higher then what your truck thinks it should be so it sets the code. I called swamps about it when i first got it and they said its nothing to worry about.
