Sir thank you for the response, that is what I have bought. I have run the tuned version plus4 and it is NICE, cannot wait to try the plus4c and the others. No comparison with my Sirio's or Trinity's. Great runtime already and still not race tuned, still some metal pinch, GREAT engine so far. Again thank you, I have been following your thread for a while now and want to say thank you for all the info.
