Density profile effects on confinement and MHD stability of currentless NBI plasmas in Heliotron E are studied. The peaked density profile produced by pellet injection increases the stored energy by 20-30% compared to the gas puffed plasmas which obey the empirical stellarator/heliotron scaling in a moderate density range. In contrast to confinement, the peaked pressure profile tends to destabilize the plasma. By limiter insertion. MHD instability occurs (seems to locate near ι/2π = 1) even in case of low β (β_0 <__- 1%, where β_0 is the central β value) plasmas. On the other hand, the mode of m/n = 3/2 at ι/2π = 2 /3, seems to be a key parameter to the major MHD instability in case of high β (β_0>__-2 %) plasmas.
