gearing & city hills

OK all, so i have a 2.88 ratio differential swapped along with the 617 into my 240D and its original manual transmission and rims. tires are 195/75-R14. i've been getting the engine running well, and it seems fine in most ways, but i can't start uphill well enough, so i think the differential swap is probably to blame. if i had kept the 3.69 diff presumably things would be easier on the low end.

specifically, climbing from a stop i can't get up enough RPMs to get any boost. the engine sort of chugs along at a very low speed, but i am pretty sure one of these days i'll be on a hill where i can't climb at all and have to bail out sideways.

i guess that without getting a getrag 5-speed my main options are another diff swap and/or smaller diameter tires. did i miss anything, or do you all have other suggestions? thanks!

(i am not worried about the speedo being off, i will fix that after figuring out the rest of this.)
