I know companies are worried about tuning the factory ECM, but from my experience these units are a simple way around this. I know when tuning these units it's based off of rpms and boost pressure. You just plug in the amount of fuel you need into the different cells in the table. Would this not work on our cars? Also as far as the compression goes. The Scion tc is 10.4:1 with an aluminum block and is able to run 8-10psi safely... so I would have to imagine this engine would be around the same.

I think I saw a post about someone trying the piggyback route. However, Vince is quickly learning how to tune these things. The problem is, once he solves one thing we find something new.
The fuel problem probably won't be any easier to solve with a piggyback as compared to programming the ECU. It looks like our low-pressure pump is just too smalll.
We've got to figure out how to bump the voltage or find some aftermarket replacement. That's my opinion anyway. I'd love to see someone try the piggyback...if it works then I'll seriously consider it myself.
