Wondering if I need more fuel

[M-technik-3]

e36 325is that has a M52 in it running the OBD-I ECU and Green injectors. Debating installing the 21 pounders and running a TRM chip for it.

Runs good and if the S50 can run fine on a 17lbs injectors I figured there would be no issues.

So in reality it's not need but want more fuel.

well the m52 comes stock with 21.5pounder.. i have a m52 OBD1 in my e30 with 21.5 injectors TRM TUNE,CAI,SS exhaust,3.73lsd,M coupe shifter.. running super hard

Yes I know that but thinking I'm not going to benefit for swapping injectors besides using more fuel.

My S50 goes lean at the top on 17 pounders.

Will take it to the shop and get some afm numbers. I need to get a wide band reader, I have been wanting one for some time. Guess it's time to pony up a few bucks.

Please post your findings.

I am running an M52B28 bottom end, M50 head, Green Injectors, OBD-I 413 ECU. It feels fine, but I have no idea what my AFR and hp/tq figures are. To put it plainly, I'm just running it because other people have done it.

Will do.
