Already tuned - instaling plenum + lower mani

Dynamis · 07-12-2020, 09:56 PM

I already have full exhaust, CAI, and resonated HFCs.

Going to throw on a plenum and mani from Z1, but I'm not keen on another tune. Shouldn't really need it, right?

Right?

To get the most out of it. You should. Plus there may be a difference on the A/F ratio. May need richened up. You will be flowing more air.

If you go ahead, let us know the difference in numbers. Curious.

Not sure who your tuner is, but Seb (SpecialtyZ) tweaked my tune for free... first, after moving from Germany back to the States (elevation change) and then again after adding the Z1 velocity stacks to my Admin Tuning intakes (not sure if necessary, but erring on the side of caution just in case).

I'd check with whoever your tuner is and they may do the same... then again, Seb is the man so maybe not.

Based on my experience it will be fine safety wise. Might miss out on a little power though.

Absolutely must adjust the tune richer. My tuner also offered to rework my existing tune for Plenum, lower and HFC's.

Should be safe (ECM can adapt to small changes and adjust AFR)* but you won't see the full potential of the new mods without a new tune.

*May not apply if you drive with your toenails getting a trim in the radiator fan
