Default New Engine Acceleration Problems

Hey guys, made it to Boston OK. 15ft truck w/ the car carrier in back made for some scary driving through the rain at 70-75mph...

Anyways, I met up w/ Scott on Sat to upgrade my ECU ROM Tune from the beta version I was running.

We ran into the same probs since mile 0 of the engine: under load, the engine will not accelerate past 3.5-4.0 RPM. Acts like a fuel cut off, it just falls flat. I can redline it in nuetral though.

On the dyno, there were no signs of vacuum leaks or bad fuel pressure. A/F looked solid at WOT.

Previous engine ran fine aside a cooling problem. Nothing has changed in terms of ignition/fuel/turbo goodies.

Can I safely assume this is ignition related? Think a Nissan consult can pinpoint this?

Jesse

PS - RPS 475tq clutch is super driveable, I love it!
