Ran PEFI flash on my 1100 and flashed a few others. Was very happy with it. Ran PEFI against a couple others and it performed better. Flash has built in protection, no idiot light ya have to be watching for detonation. Doesn’t run as lean as a few others. Paired the flash with Jaws full exhaust system and the sled pulled really hard and was problem free.
In some other forums I frequent Speedwerx was not the first choice. Several others were more popular for whatever reason. I went with Full Throttle Speed and have been happy. Lots of protection built in and it has the deto light. Can switch on the fly between 220 and 260.
I have a tendency to get into trouble at 260. Sh1t happens fast at that power level. lol
