Default Pre-purchase question

I have started reading thru the MSPnP threads to get familiar with the issues you guys are seeing. I do have one question that has kind of been answered, but I am seeking advice.

I have a GReddy TD04, RX7 AFM, 255 HP Walbro, 440s and a Vishnu dual-feed rail. I am looking at the MSPnP with the upgrade to delete the AFM and add a wide-band O2. My question is this: Do I really have to return to stock to get base readings Before I add the MSPnP (and then put the all the turbo bits back on)? It'ssuch a friggin' PITA to remove the rail and injectors and put everything back without leaks!

No, not as long as you have the wideband. It would be a very good idea to spend some time on a dyno to get everything dialed in.

You definitely don't need to return to stock by any means-- the MSPNP manual goes over what you'll need to update in the base map to get it 'in the ballpark' for your injectors, and then as KOL suggested I'd highly recommend some dyno time to dial it in just right for your setup-- you'll be very happy with the results...

I would do just that. Thread drift did you ever get your car running right did miatamimi end up helping you or are you still stuck missing 80 of the whp he got out of it?
