I haven't got a Dyno lined up, I figured if there was any interest I was just going to work it out while I'm over there.

To be honest Leeroy, if G&D have "built a bit of fat" into the program, there really shouldn't be any need for a re-tune. That said, you may stand to gain a few kW's and Nm (as little as 3 to as much as 10) from optimising the tune for the intake... It all depends how good your new intake is and how bad the old one was.

The beauty of these intakes does not show up on the Dyno, it all happens on the road (and strip)... Some on road tuning would be a good thing!

I assume you went MAFless???

EDIT: I just re-read your post. A 3.5" intake pipe would be holding it back, and if it's that wire supported convoluted type flexible pipe, I would definitely get it re-tuned...

I'd be happy to take a look at it, but chances are they have locked your PCM.
