Gonna Get Tuned Think I Should Get Bigger Injectors- What Size Should I Get?
Well I've finally finished my power mods about as much as I plan to do at this point and I'm ready to get a tune. My thing is that I'm using STI Pinks and I'm concerned about maxing them out so I wanna something larger in there but I don't wanna go too crazy. What size injectors would best fit my application?
*Quick mod list* P&P VF-43, STI pinks, Walbro 255 fuel pump, Tial 38mm EWG with Ultimate Racing UpPipe, Bosal turboback exhaust modified to fit with EWG setup and QTP exhaust cut-out installed, P&P heat- wrapped stock header, PIT EBC, Open Source Tune.

i would go with dw750's that way you will leave some on the table if you add mods later.

I was thinking about 750 is probably good...is there such a thing as going to big? Is it harder for the tuner to tune if I get injectors that are much bigger than what is likely needed? Like maybe 850ccs?

Larger injectors can have some issues with idle, but 850 should still be fine, might want to bump up the idle a couple hundred rpm.

I'm not familiar with NJ gas (other than you can't pump it yourself), but is there any E85 around? Have you considered running that? If you do consider it, then you may also need to consider even bigger injectors.

My car's a daily driver (100+ miles per day) so I don't see E85 in my future

DW750's are the best value upgrade injectors, arguably the easiest to set up correctly in RomRaider and they will support 400whp on pump. If you ever plan on running E85 in the future though (or getting alarger turbo) then you might want to look at DW850's at a minimum.

Dont go with 800's. Make it 750's or 850's. If theres any possibility of going with more parts later get the 850's. I ran 850's with a stock mount gt30 at wg boost (14 psi) around the 300ish whp and idle was perfect..

No..I don't mind. My job is an hour North of my house and the closest E85 pump is 20 minutes North of my job. I don't think E85 is very prevelant in my area yet. But I'm open to thinking about this if E85 is more prevalent than I thought.
