    You may want to look into getting some larger injectors and a have it tuned for them as well. When you have it tuned depending on which injectors you use I would ditch that FMU if you can. Those things are worthless IMO!

    You should check your fuel pressure and see if it drops off at WOT. You fuel pumps may not be able to keep up if you inj DC is turned up too high. Methanol is an alternative to going anything over 60# injectors. I'm using 50# inj and I was running out of fuel at 8 lbs at about 4500 rpm until I bought a meth kit. Not too mention its a lot cheaper than a set of low impedance injectors and a converter. Plus it will lower your IATs some
