Hi,
Look at my scenario below. R1 and R4 is connecting to each other via
serial and dialer profile with eigrp 100.
r4#show ip route
D EX 150.1.1.0 [170/2297856] via 10.100.100.1, 00:00:57, Serial0/0.1
r1#show ip route
D 150.1.4.0 [90/2297856] via 10.100.100.4, 00:12:35, Serial0/0.100
r4#show int di0
Dialer0 is up, line protocol is up (spoofing)
Internet address is 10.120.120.4/24
MTU 1500 bytes, BW 56 Kbit, DLY 20000 usec,
r4#show int s0/0.1
Serial0/0.1 is up, line protocol is up
Internet address is 10.100.100.4/24
MTU 1500 bytes, BW 1544 Kbit, DLY 20000 usec,
Now I change bandwidth under di0 on both sites to 1544.
r1#show ip route eigrp
150.1.0.0/24 is subnetted, 7 subnets
D 150.1.4.0 [90/2297856] via 10.100.100.4, 00:01:27, Serial0/0.100
[90/2297856] via 10.120.120.4, 00:01:27, Dialer0
r4#show ip route eig
150.1.0.0/24 is subnetted, 2 subnets
D EX 150.1.1.0 [170/2297856] via 10.100.100.1, 00:02:16, Serial0/0.1
[170/2297856] via 10.120.120.1, 00:02:16, Dialer0
Then I changed delay under both di0 to 25000 usec.
r1#show ip route eigrp
150.1.0.0/24 is subnetted, 7 subnets
D 150.1.4.0 [90/2297856] via 10.100.100.4, 00:00:36, Serial0/0.100
r4#show ip route eig
150.1.0.0/24 is subnetted, 2 subnets
D EX 150.1.1.0 [170/2297856] via 10.100.100.1, 00:01:48, Serial0/0.1
There are many good resources from many sites. But you can check this first

Not sure if you are looking for this :)
