Matched Inlets worth doing along with group n timing ?

[finch wxm]

Is it worth getting this done to mine prior to getting group n timing and map at Efi ?

Anything else worth doing along side it ? Running a miltek and decat.

Group N timing on its own will give a slight increase in bhp so every little helps as they say.

I've seen some very optimistic claims for bhp increase due to fitting matched inlets. In reality don't think any minor increase gained (if any!) is worth the effort and cost. Then again its not my money!

They're relatively cheap to do, and there aren't many good VFM mods for the engine.

Does getting the throttle body enlarged have any proven gains ? I'm just wondering if i should be doing all this prior to mapping to get maximum gains or is it just an extra waste. Also lower inlet RS stamped any difference if getting ported ?

Not worth enlarging the throttle body.

The stock inlet can only flow so much volume.

No difference in lower inlet if getting it ported.
I’ve always been under the impression that the throttle body is a gimmick but happy to be told otherwise!
