Hey all, Just got off the phone with Bob Romano and he tells me that my siemens 660cc injectors I purchased in the group buy will be no good for my T. Im aiming for around the 320-330rwkw mark . What should I do? im thinking maybe I should start lokking for a new tuner, altough I really dont want to.

Mate, there are good Brisbane tuners right here that sponsor this site. Talk to a few of them, then make your decision about if you want to move from your current tuner. I cant comment on Bob Romano as I have never been there, but Steve @ RDP is who I use. Another good one is Paul @ Elite. Talk to these guys, both genuinely nice guys to deal with.

Cheers

Jeff

No such thing as too big with these injectors.. Theirs are by far the best big high impedance injectors you can get.. Very linear flowing injector, and very controllable even at low pulsewidths.

I've even run these injectors with the stock calibration (ie, only the injector values changed), with no problems.. (that's how I scaled the first set)

But if he suggests dont use them. Well heck, he obviously doesnt know how good these Deka's really are..

In comparison.. Nizpro's drilled injector are approx 60-70lb in size. They run them in the kits upto the 300rwkw mark.. But have plenty of head room incase you want to go further with their kits.. That way you dont have to change injectors again later.

Anyways. I would personally be putting the Deka's in.. If they have trouble tuning it.. I'd be looking for someone else to tune it..

There's a saying.. "You can never have too much injector"

Sure, these injectors are able to supply more fuel compared to the power figure your chasing, but.. Who knows what your gonna do in the future when you get sick of 330rwkw :)

He's prob' thinking theyre some oldschool single pintle injector that back in the 80s/90s were hard to get a smooth idle from... these are fine, heaps of headroom for 330kws...

My guess is he wouldn't have a clue where to start with the scaling, so is palming them off as "no good" or there's something wrong with them..

Go find a tuna who knows what they're doing!!!

exactly :)

a real tuner would say. Hrm.. 60lb.. standard about 30lb.. Lets try doubling the hi and low slopes and see what that shows stft/ltft and AFR's

lol

:)

C&V have no problems tuning with these injectors (see billsta's car)
