it appears to have been running lean. when i got the injectors cleaned b4 use they told me two werent pulsing. even though they were ok when they came out. when he went to show me that they were not working they had come good. he said maybe because they were in the bath ova nite. or i also put xf throttle body with closest t.p.s i could find, it was very close to original but n.q.r. but i dont think this would be a problem. just needed more fuel i think. there was no pinging or any signs like that. i kills me to say it but a good dyno may have saved the engine. ive gotta get some injectors b4 it goes on the road again. im thinking sard 550cc cos greenline have a special at the moment. anyone seen any cheaper? they also have 850cc for the same price but it may be ovakill. rb30det, cooler, t3/t4 hybrid. custom plenum.
