How's drivability? Any downside? Figure if I'm gonna upgrade I just as well go big for e85 later if I choose. 60s are maxed out with alky.
 
I have the SMP 120's and never had a problem with gas/alky. E85 for 2 yrs now and still no issues.
 
No problems here. 120 SMP injectors.

Drives just fine, and no issues on either a regular 6.1, extender, or SD2 chip, MAF or MAFless.
 
Same here 91 pump w/ SMP 120's (got em from Eric at Turbo Tweak) and XFI no issues. Idles and drives fine

Lemme get this straight....you're going to (finally) buy larger injectors....and you're considering having a 93 chip made for these.... when you have E85 within a mile of your house.....makes zero sense to me.
