Just installed the said FMU on my '99 Solara this past weekend, first Solara that I know of to do so, but had a question for those of you with experience on this product. Once we fine tuned it, we noticed that under load, the fuel pressure does not increase instantly. Understand why after the fact, but around 2500 or so on up, my correction values are near +/-0, but below that, they range from +15 - +32. Just wondering if you guys have used anything to help correct that?
