That sounds great. What engine and induction system do you have? Is it an FE with the TWM induction?
Awhile back, one engine builder I know could never get that setup to work perfectly. It looked great but couldn't get it tuned correctly even with a visit to Electromotive.

It's an FE. Dual quad (with two sets of butterflies in each "quad") with separate plenums. I use a chamber connected to each plenum for the MAP sensor and I have the remote TPS just like you'd need with a TWM setup.. It's not 8 IR's, two sets of 4. It does have 16 injectors (2 per port, staged).
To summarize, 4 sets of butterflies (versus 8 with TWM's) all of which need to be set, adjusted and coordinated together, progressive linkage, 16 staged injectors (so not only do I have secondary throttle blades opening, I have tertiary? staged injectors coming on line as well under full throttle). I tuned it myself. It not only runs great, it passes emissions and gets great mileage too.
So, what engine builder couldn't get it tuned. This is a forum to share such information so that we can either support or avoid such builders.
Good thing I didn't hold my breath waiting for a response or for someone to name names...
