I ran them for awhile on my stock obs
The highest 2 tunes would surge if you held the pedal down too long.
The other 4 tunes were no problem.
I should note it was a brand new stock replacement pump put in at the same time as the d66 and 238's.
You'll be fine for a little while if you can restrain yourself.
Just keep it out of the higher tunes or you could damage the plungers and barrels from bottoming them out due to the low fuel pressure.
