I have an HPI rs4 3 with a newly installed 2 speed transmission. the engine has been through about 8-9 tanks of gas roughly half a gallon or so. the problem I'm having is that the car doesn't start to move until the throttle is opened about 1/4-1/2 way. once the car gets moving it performs much better but its like i have no acceleration. i desperatly need help in tuning this the right way. i have the stock .15fe engine and the 2 speed installed. thank for any help
