Noobish Boost issue
Alright writing this for the second time due to the computer restarting after window updates
Well I have been tuning and tweaking on this mspnp for about a month now and feel I have gotten the hang of it. I would like to thank a handful of people on this site for that. I feel I finally have gotten to the point where I can get on it a bit more and see what my old girl can do, but there seems to be an issue with boost. When I ease into the throttle boost builds slowly but surely but if I step on it boost builds for a moment then falls on its face. I thought maybe the boost protection cut out but that is set at 200 so that can't be the issue. I have done some searching on here and other sites looking for a possible reason why this happens but still haven't found a answer yet. So I figured I would make a thread and ask for advice from the experts out there to see if they could point me and my car it the right direction for maximum boost. I also am including a current setup on my mspnp as well a most recent data log which looks like I have a recently lose ground somewhere. The reason I say that is the last data log doesn't have any noise in it. For those of you who are looking at this a little help would be great. Thanks Tony
About the setup:
91 miata stock mtr
t28 churbo with 14lbs waste gate
afm delete w gm sensor
intercooled
vtps
diy dual feed rail
460cc injectors
lc-1 wideband

Alright this was the best I could do to show the problem but any help with the problem or something you may see that isn't looking correct give me a heads up. I'm still learning. Thanks Tony
If these pics don't work then give me a heads up and I'll find something that does.
