Dinan Engine Software Extended to '06
 

According to Dinan's site, the now offer Performance Engine Software, Stage 2, and Stage 3 Engine software for vehicles up to 2006.

Is it a typo?

Does it really have an effect?

IMO the software will do little to nothing unless used with either at CAI and/or Free Flow Exhaust. Otherwise, don't waste your money.

I have both the Dinan intake and the exhaust.

I tried the powerchip and the mods above didn't work with thier re-mapping and I ended up going back to stock programming. If Dinan has these bugs worked out, I might give it a try.

In that case, I would say the Stage 2 is required. You should really see/feel a change with the Stage 2.
