I am in the process of putting the 700cfi from my 07 rmk dragon into an 08 chassis. Both sleds are complete as of now, my 07 chassis is beat, the 08 motor is low on compression. Question is are there any improvements or benefits to the 08 electronics? I've heard the 07s run stronger... I'm assuming the only difference is the ecm mapping? Which one should I use? My 07 runs great, don't know about the 08 other than it runs as I bought it as a parts sled. Both have the yellow injectors and I do know that they both have the updated voltage regulator installed...
