los91 i was in the same boat u are in.....sounds like to me that u are letting the rpms drop due to the low et....but the gearing is about right for your weight...biggest thing is gonna be is SEATTIME.....listen to these guys they know their stuff and be patient...turbos area different ballgame trust me and im still learning

i was thinking about a 2step but didn"t know if it would work on a turbo bike ..its so hard to hold 8000 rpm without letting it drop so that might be a good idea.i need to learn it at 10lbs before i get a ams1000 and go to about 20lbs

Did you flash the ECU with EE for gear map in N? This will dump more fuel in the motor to spool the turbo with no load with the clutch in. Neutral map (clutch in) trims fuel and will take longer to get into boost when launched.

Good luck

New guy here with the same problem. Recently picked up a low miles 03 Turbo running 8lbs and low comp pistons. Horrible 60ft 1.9, and only trapping 117mph at the 1/8. Hitting 147 out the back and 10.0...having someone watch me at the line it seems not only is my rpms dropping I'm not getting it open as I slide the clutch out. I'm also stock gearing and 235 without gear.

thats the key tommyv...gettn the throttle pinned off the start....when its not done right you will think something is up with the bike bt 90% of the time its the rider...when u get a low 60ft the bike will not run any faster than a stock bike and u will be like wtf is up lol...it takes time bro the power is there we just got to unleash it
