Little Lag time in response..

[Chucke.b]

Took my Spark out this weekend and noticed a bit of lag in the response time with Vtech tune.. it was so aggressive before. .this weekend just seemed a bit sluggish on the response. Any ideas?
Looks like wear ring is fine ( Riva stainless ).
Fuel possibly? Plugs? It just hit 50 hours so due for oil change and plugs anyway.
Thanks in advance!

Are u putting it into sport mode? The touring mode on the vtech tunes has AlOT of throttle delay. The vtech sport mode is instant throttle.

Yep.. Vtech only works in Sport Mode.

Yep.. Vtech only works in Sport Mode.

huh? where do you get this info from?

The v-tech tune on my SPARK has a 'touring mode', as well as a 'sport mode'

there is no 60hp cruise about mode any more. Its all 109 hp; only difference is in throttle response time.

[Chucke.b]

Mine has a touring mode as well. Maybe its just throttle response then. ( But Im talking about Sport mode.. )

can be numerous things... does it hit rev limiter easier than before?

I have seen a photo where some one had a small piece of wood cut and stuck onto the front of the prop maybe worth a look with a torch to see if something stuck on the prop

[Chucke.b]

Its reaching 7600-7800 RPM / Top Speed is normal 50-52 mph.

What tune you running ??
does sound a bit low
I would check and clear any errors codes first then see.

I had some throttle sensor problems it would through a check engine message then go but I noticed it didn't go in limp mode, but it did drop about 500rpm to 750rpm sound like you too

Running the IBR 8750 AGR tune.. the only one available for IBR. Bad thing is I dont have the tuning module.. I had a shop put it on. So cant check for codes.
Also running Solas 12/17 , Riva Stainless wear ring, R&D Intake grate, WORX rear exhaust and a gutted water box.
