Chiping stock ECU or Gressy e-manage ultimate

[lilpiton]

Ok to start of i have an s15 sr with stock turbo, full catback, a FMIC turbo mani and thats about it, pretty much stock. So i got a good deal on a greddy e-manage ultimate with z32 MAF for 300 bux so i picked it up and still need injectors. but now ppl are telling me to just got like with a JWT ECU and be done, and then maybe get a SAFC for some self tunning...Now I dont know which way to go. Cause the e-manage will take good couple of hrs of tunning so that will cost another good couple hundred bux but will give me ALOT more options to work on with the ECU other then just air and fuel like the SAFC will... Im trying to get your oppinions on this one and will see what I get and will decide which way to go from there.I thought that i may be able to sell the e-manage for a better price then i got it and but the injectors and will just have to save up for the tuned ECU. the down side is that JW is a 2 month wait as far as I know...Thanks in advance!!!!
