I've been in the repair industry for over 35 years. I have 1990 K3500 454 T400. I am looking to upgrade the engine power past the point that the stock prom will work. So I been reading as much as possible and I think I've got a good handle on this tuning thing. I recently purchased and installed a EBL Flash from Dynamic EFI. I'm real happy with it.
Ill be doing some upgrades with heads cam and intake. so the ability to tune is a must. I'm sure all the info will come in handy.
Thanx Byron
