so on my 13.025 run at about 5200RPM It acted up again
for about 1.3-1.5 seconds I had my foot down and was like FUCK.
so I let off, and hammer back on it and its fine... wierd and I still ran that time
tthis isnt some BS I made up
im going to get a screenshot of the Datalog
I wish I knew the problem
1 thing i know is im running slicks next week and im going 12.6

the probable causes I came up with are
1. The location of the Map sensor (new one) is tapped off the side of the intake right between the ports, so possibly at higher rpm there is so much turbulence its not feeding the line to the Map properly
2. an electrical ground isnt dont up correctly, this problem is very intermitten but only happens at HIGH rpms (4000+ Generally)

if anyone has any idea its a TPIS Mini Ram II with Holley Commander 950 DFI and a single bar map sensor

Mike, could you replace the MAF with a speed density system?? Not that i know a lot about this but Chevy got rid of them in 1990 after using the MAF from 86 (I think) on.
In the 1990 305 F code engine they went from 195 to 210 hp by changing the pistons and go to the speed density system.
Just wondering if you know more about it???
