Learn Spanish (Spain): Aunque necesitamos el dinero, no pedimos el préstamo. - Although we need the money, we are not asking for the loan.

When aunque is followed by the indicative, it means "although" or "even though" and states a known fact. If it were followed by the subjunctive (necesitemos), it would mean "even if" we need the money, treating it as a hypothetical situation.

Why isn't there a word for "for" after pedimos?

The verb pedir already means "to ask for" or "to request". English speakers often try to add por or para to match the English "for", but in Spanish, the preposition is already built into the verb.

I thought pedir was a stem-changing verb. Why is it pedimos and not pidimos?

You are right that pedir has an e-to-i stem change in the present tense, giving us forms like pido and pides. However, just like most stem-changing verbs, the nosotros and vosotros forms do not undergo this change in the present tense, so it remains pedimos.

Could pedimos also mean "we asked" in the past tense?

Yes! For regular verbs ending in -ir, the nosotros form is exactly the same in both the present indicative ("we ask") and the preterite past tense ("we asked"). You have to rely on context to know the timeframe, and here the context of necesitamos (present) suggests pedimos is also in the present.
