It is a lot easier than trying to burn own chips. There is a main thread (as well as several smaller threads) on thirdgen.org that deals with EBL user questions. Unless you have a fire breathing monster of a camshaft+engine EBL can handle.
I run EBL on all my conversions - see youtube videos. The key to TBI is selecting camshaft that provides about 14-16 in-Hg at idle and steady idle. After market camshaft with LSA of 112deg and higher with up to 214deg at 0.050 will do the trick. Tighter LSA (<112deg) results in lumpy idle which screws up MAP sensor readings and ECM will over fuel the engine. Long duration camshafts >220 deg also create havoc for O2 sensors at idle. Our trucks need low end torque, and high RPM HP is never really needed in a street truck. What we need is flat torque from 1500 to about 4500 RPM to get the weight going (and keep it going). A good RV cam will do this trick without creating problems for TBI system - for example CS1014R (flat tappet).
