Dyno Testing the 2022 Grom with the TST Worx Airbox Cover and the Tyga High Mount Exhaust

Fun evening at Riderzblok dyno testing my stock 2022 Honda Grom, and then running it with the TST airbox cover and the Tyga high mount exhaust. Both made impressive gains at important parts of the powerband.

I'd love to see more dyno testing of the 2022 Grom with various mods and combinations compared .

[Myrussell]

Great job. That is how it’s done to see exactly what the mods are doing. Would have loved to see the fuel tuner along with the intake and exhaust but still “well done”

[teknique]

3:50 they say stock is 8.7 then at 7:29 with intake and exhaust is 9.6 so he gained .9hp. Nice!🎉🎉🎉

[reidspeed]

Nice, I guessing the numbers would go up as you put miles down, ecu learning

[StayTolerant]

Are you still using the same air box/tyga setup today? Are you still liking it as much as day 1? Thanks for the great content.

First, thanks for putting them on the dyno. I just installed my TST Worx Airbox cover and reset the ECU and it does feel really peppy especially in 2-4 gears. 5th still struggles due to power. But, when you are running the changes on the dyno are u resetting the ECU each time or just stock ECU? Thx mate

[SSS-mpth]

Would love to see this after a tune to see what the difference is. Just finished my intake and cam install and waiting for my ECU to come back from DHM (2022 Monkey).

Do you know of anything that can be mounted on the left side of the bike in the two bolt holes the stock Monkey airbox uses? I'm thinking of trying a Gcraft rack with some sort of extension.

[roberthelvick]

Have you ever ran a test to compare the tyga high mount to a yoshimura exhaust set up ?

[roberthelvick]

Have you ever put it back on the dyno with the intake, tyga exhaust and the dhm cam ?

[MetalHDGMR]

i notice with the yoshie they curl the pipe midway to maintain that backpressure and its titanium so if you had that you wouldnt have lost that power in the low end with intake mod. I plan on getting airbox mod.

[PharaohKoup]

So i noticed on the Dyno A/F ratio was sitting just below 15. in your previous videos you suggested 13.5. has anything changed or is that just the factory mix.

[DriftingLifeSideways]

Is this a safe setup to run with no tune?

[bakotako]

also, this may be a dumb question but i think others might be interested too. which full system performance exhaust would u recommend, yoshi or tyga? the reason i ask is one is $422 and the other $650. and also any other performance exhaust? thx mate again

[Grainsauce]

When adding the intake and exhaust, was this with stock tune, if so I wonder what a reflash would do.

[bakeot]

So no tune and it pick up 1.5 hp how was the fueling did it run rich or lean??

[patrickmarkos]

What does your bike make with the exhaust, worx intake and dhm cam?

[evinrassier]

Can I rock the tst intake and exhaust without a tune for a bit or too risky? I realize I need a tune but should I immediately?

[cyrilbaillif]

Hi, i have a honda monkey 2022, I changed the ECU with another original ECU. Now I have my check engine light flashing continuously. anyone have an idea of ​​the problem? Thanks

[tonymontana]

stock air filter behind the tst airbox cover??

[rickstar]

@eastcoastish what kit is Doug running can you send me a link what else does he have to get 14.7 hp eg cam head work injector intake exhaust it has very good throttle response and it is very quick rpm between 2k 9k rpm I would like to build my grom motor like this he’s saying that it only has a jug and a oem Honda piston he would have more work done then a 140cc kit to have that throttle response could you please let me know what work he has done what parts I need thank you ricky from Australia
