Hi all,

I didn’t see a post about this and think that it might make some in CA more comfortable. Before I put MHD on my car, I wrote to them and asked if flash back to stock would work for a smog check in CA. MHD said it would. The smog police check the DME data against the last test here.

I can happily report that I flashed back to stock last weekend and passed my check this afternoon.

Now to get the Precision Raceworks fuel pump installed and flash the tune back in. This time with an E50 mix!
