ya with ppe hot et 2 you can completely remove the rpm governer if you want to but i don't like the idea seeing i did it one day and forgot about it and went into a really hard throttle and nearly choked when i looked at my tack pushing 5k rpm's,i didn't really gain much over 4k rpm's due to it runs out of fuel and air at that many r's but i'm thinking with more fuel and bigger turbo it would bennefit for more speed..hope this helps
