No problems at all. This mod really changed the top end pull of my car. I think I had everything else in place and the intake manifold was the bottleneck.

Cool! I might give them a call this week. I’ve seen others mention that there were plastic flakes in the intake after gwatney worked on it. Did you have to clean your intake when you received it? Thanks for the update!

Any comparisons on Futral vs Gwatney? I thought there were only 2 places that did this work and I've never heard of futral. Thanks for the suggestion!

I wonder if any company has experimented with the rodmod on a Fast intake manifold?

Good question. My question is; "Are the FAST and the OEM intakes similar enough internally where it's even possible?"

In any case, at the end of the day it may be a better/safer bet to simply go with the mid-length intake runners that FAST offers versus modifying the intake with the conventional length runners.
