    The base riva flash is solid, it basically just removes all the limiters. The AFR is solid as well. In mild air/water temp it runs around 8100-8200.

    If all your looking for is 3-5mph why don't you just get yourself a scom and save some money? JP Racing has a flash for less than a Maptuner/Riva Flash that'll put you over 82mph with no other modifications.

    No way your getting to 82mph gps with a flash only, especially in Florida. At least not on in any normal circumstance of weather, fuel load, rider weight.

    Yesterday I saw 78mph(75gps) on dash at full tank of gas at 8100rpm with the base riva flash, stock everything else on my tx...except riva sponsons. On low fuel you can get 78GPS. Water temp was 66F/Air temp 77F. Get the Maptunner its a nice setup and at least if you get some other parts you can flash it up.

    You got some learning to do bud. Go check him out if you don't believe me. This is the same guy that just tuned a GTR X to 81mph (GTR X had Cam, supercharger upgrade and supporting mods).

    Not sure how you can compare a cam, supercharger upgrade, supporting mods to just a flash. 81 is probably very doable with those mods but I donít know much about the gtrx hull and itís performance. Flashing skis isnít really turning by the way. For the higher levels of mods, Most flashes are less than ideal and usually only get optimized at WOT. Iíve seen more than a few logs of flashed skis and they are usually a mess other than the cells at the top...but most people will never notice...so maybe it doesnít matter. Iím a fan of the low level flashes but i personally wonít run the big power mods on a flash..at least not unless I can adjust it. Since I have motec ecus I wouldnít bother with a flash on a big modded ski. My bud has an 85mph tx with a motec cam and bug charger that I tuned if you want to come out and play one day
