If one hacks into the ecm via VTech and tweeks the ecm can the dealer detect changes have been made even after the factory settings reloaded?

yes, if they look
if you drop a valve you can bet brp not the dealer will want a ecu data download

How far back would the data be stored? Max rpm for the last ride ?

I think the last min or 5 mins of history on ECU.

You will need injectors and a way of tuning, easiest is to get a Vtech tune and injectors and download the tune for the 68/140, make sure you watch your afrs or get a logger as you may need to adjust the tune

can someone list a order for all of page one, like which one to do 1st and then the best mod to complement the 1st one and so on. it seems to just suggest these mods are available. have other company's have staged setups, and they differ from one another, just to see what has worked for everyone

First is to unlock ecu and remove limiters then Air intake upgrades IMUK, 4” air etc. Prop to make most of newly unlocked ECU. From there the ski is the limit

Have a look at the staged kits for your ski on this page of the forums store. This will give you some insight on which parts need to be done together. The staged kits are a great idea, they have matched components that are meant to work together.

It`s very interesting

how worth it are the different power mods on the 260's? when i looked at it it seemed you'd be spending 5-6k and 300's can be bought with stock higher hp and better mod/$ potential for under the price of making a 260 as fast as a 300 with a scom.

edit, this assuming a $7500 value on a 260 rxtx and a 10-14k value on a 300 depending on model, both used. new the 300 is going to be much more.
