Got the Dips

[ohdavy1]

Last week I installed a new SMIC, SLS hot-pipe, custom cold-side pipe and Mid-pipe. After a few test runs, I noticed after the car is completely warm, when I shift into neutral the rpm's will dip to around 100-200 rpms and then recover back to 700. Wondering what protocol/troubleshooting areas I should consider to fix this problem. Seemed like it got worse after a seafoam too.

relocate the maf. Search it

Even without BOV?

If you have a BOV mounted after the MAF then this is your main cause...

Ya, that's what I thought. I'm running the stock BPV, not a BOV. So I'm thinking this isn't the problem
