I've done some testing of all 3 P-38s. climbs were started with 75% fuel full ammo no external stores from a standing start with clock starting at break release. Top speeds were done via quick missions starting with 75% fuel, wind effects were disabled, engine over heat turned off, radiator was checked at various openings, down low the radiator appeared to have little effect, but as speeds increased at around 15,000 ft and up settings of 4 or less netted a few extra mph.

I could not get the 38L-5-LO to 40,000 ft it lost too much power

just thought I would throw some numbers at you, I am sure my climb data contains the most errors. I found climbing at 170-180 ias down low and letting it drop to 150-160 mph ias at 25,000 ft gave the best climb rates. I believe this is why the 38J climbed too slowly because I only indicated 150 mph or less during the entire climb, further testing of the J needs to be done.

my tests show that the rate of climb is low at all altitudes for the 38J and 38L-1 (not sure about the L-5). they also show that at altitudes above 15,000 ft all 38s are too slow and that down low they are very close to real life numbers published in many books. My tests also show that all P-38s loose hp too soon and it drops off far too quickly than real life numbers published in many books.

I personally do not care if it gets fixed or not I was just bored and decided to dork about.
