20 Riot, 21 Riot.
I was a little bit hesitant as well. But when I called and talked to them, they told me that the flash that I was getting it was for the new style head mod. They said they wanted to do a little more field testing on it and that they possibly might tweak the flash a little bit before releasing it for this next season coming up. The domes do lower compression a little vs stock, but not as much as the “original” LTS. I usually run 10% ethanol 93, but some places only have 90 oct non-ethanol. I keep some octanium in my tunnel bag in case I fill up with 90. Wife and I did an overnight trip late in the season and had to fill with 90. Temps got up into mid to high 30’s on way home and I was running it hard. Thought I heard it ping a few times. When I brought it to the shop to put it away for summer I hooked up the Catt 2 tool to it and it did pull timing 3 times that day. But not enough for octane code. Don’t think that would have happened if my flash didn’t have more timing.Im waiting to see dyno results from the domes. They dont list it online or facebook. They told me it would need more timing than the head mod. Because its cut like an lts mod.
So it will have lower compression than the head mod and less hp since it has not been dynoed and they have not adjusted the flash for timing to accommodate the head.
