Tuning a '98 C1500 4.3

[Sarge]

Not an LS motor but I thought I'd see if anyone has an answer.

I've been surfing around for a while trying to find something to tune my truck via laptop. I want to do two things. Get familiar with EFI tuning and get a few more MPG out of my truck. With Tunercat not available anymore, What can I use?

HP and EFILive don't support my application.

Here is what I have:

'98 C1500 ext. cab
4.3
5 spd
Flowmast American Thunder cat back
K&N drop in filter.

Thanks,
Phil

I just found out EFILive will be releasing the cal files in January for the 98 and 99 Vortec PCMs

Yeah , beat me to it , EFILive will do it in the next few weeks .
I think you will need the V2 of EFILive , which does Duramax with no problems as well .
