    I've been researching HPTuners vs EFILive to dive into this thing. This BlackBear place has a good reputation and they use EFILive stuff. But HPTuners is cheaper and that would save me some cash vs...

    Stock Vortec head, 207@.050 LT1 cam, Edelbrock Performer manifold combo. I think the biggest thing making it feel lazy was the steel wheels. Borrowed a set of aluminums once and I was amazed at the...

    Narrowband not agreeing with wideband

    I've got a WBo2 gauge in the dash and I always glance to confirm I'm 14.7ish. I'm having intermittent issues with it dropping to 13 or even 12:1 during normal light throttle driving and idling. The...

    In $OD there's an altitude spark bias that will drop you by about 10 degrees. I had that issue with mine. I'm not sure what triggers the bias, but I zeroed it out a year or two ago and it has been...

    I've been tweaking my 94 for 10 years and am actually rewiring my new 92 to be a "94" now, too.

    Post up a log and let us know what's "not right."

    I'm not familiar with $E6, but on my $A1 I had issues and found out the "body size" was wrong. I emailed Moates to get it figured out and they were helpful.

    TPI injection with Vortec heads

    I know SD makes a base for $400, but that takes the "budget" aspect out of my TBI to MPFI project. I'd planned on using my existing Vortec carb intake with TBI adapter and fashioning my own rail...

    Not sure if that manifold has a spreadbore pattern, but I went from the thin adapter plate to the BBC adapter with coolant running through it for better cold weather driveability.

    The bungs are longer than they need to be. So I am going to drill the manifold all the way through on the mill at work. Then I'll set all the bungs at the same depth and cut them off flush with the...

    Thank you thank you. As long these "Accel" injectors are actually the Ford ones that should put me in pretty good shape.

    Anyone have thoughts or tips on the repin process?

    I measured my injectors and they are 14.5ohm, so I'm good there. Would still like the know an estimated offset if anyone knows how to figure that out.

    However, that new 94 truck is a rusty POS, so...

    Interesting stuff. I actually just bought a 94 truck with a blown 4L60E and have a friend with a free 95 4L60E. I was wondering if I could just turn all the TCC stuff off in the BIN and use the 95...

    I just googled the stock TBI and it's quoted as good for 450-480cfm. Is this figured with fuel spraying through it? Carbs too? Cause the fuel itself takes up space.

    Tuned Vortec TBI to MPFI on 7427

    I built a Vortec TBI in 2011 and tuned it so it runs pretty well. A little bit lazier than I expected to be honest, but the BLMs are all really good and driveability is good.
