That's what I was planning to do. Slowly increase power step by step. Learn to handle and treat it with each step of power up.
As for whether I have been in a high power honda. Not a honda. But a very nice large 545 big block chevved ford coupe. Once you've been in something that goes 0-100 in as little time as it does. You get hooked. Bad.
However. As for the ecu swap and harness cut.
Would a stand alone fuel management work??
