Gordon at Witchhunter can match perfectly if not to one half %...... NOT on the ones you send in. I bought a set off him and got 831,832,831,833 for 240.00 shipped. Then when I switch them out... he will give you back 110.00. Or I will sell them on NASIOC for 150.00 (which is better IMHO).
c2bcoolwrx, I just talked to my tuner about that. They actually tried modded injectors and DW injectors on the same car/same mods. The car (they said) actually did better with the DW. Not knocking the modded stockers or anything, just putting my two cents out there also since Im looking into this.
Yes, but at idle, start up and just around town, the modded injectors werent as "smooth" as the DW, or so they said. It kind of makes since when they explained it. But Im no professional or expert at this. Just was was told to me.
Let me add something to those posts guys.... I can actually tell you that each individual tuner has his preferences and has "set/base" maps and works from there. Dynoflash is notorius for this. So one may not be "better" than the other... the tuner may not want to work out ALL the bugs because we all know TIME IS MONEY. That's why they tell you to ask your tuner what KIND they "prefer".... I say it's lazyness on their part.... Keith from AWDTuning in Dallas told me it didn't matter, he will work out the kinks in any injector.
Bet you they weren't flow matched... And if they were... the gaps between the 4 were WAY off.
