I built my car 13 yrs ago and I'm trying to bring it up to date. I'm installing the AEM wide band, powerlogger, and Alky. I will need to have Eric burn me a turbotweak chip to run in closed loop with the WB. My question is, do I have the 55s maxed out, should I go with the new 80s? My build is in my signature. Thanks!
 
With alky you should have plenty, What boost/ power level are you wanting and are the heads ported. I went well into the tens with 55# injectors + no alky
 
I'm shooting for around 25 lbs of boost. Heads are not ported. I'm hoping for some 10.70 to 10.50s I also have Red's double pumper.
