Fat-Tony Member 5,364 Member For: 18y 10m 3d Posted 07/05/08 09:45 AM Share Posted 07/05/08 09:45 AM My Nizpro items that were removed were hardly precision drilled. Some of the holes were oval, visually neither hole was the same size as each other. I could swear they were done with a hand drill. Don't know if there was a reason for all of that, don't care, shame I didn't get a good pic for ya all to see. Fuel economy is better since putting the dekas in also. My expirience.

I have a low rwkw figure..... I have FANTASTIC fuel economy. If you have dekas guys... dont panic... they do the job and they do it well.Ditto Jetters, I have just driven 2500ks in the past 4 days, 90% highway with a few solid bursts for overtaking and have returned fuel economy of 9.2l/100km. Also bare in mind that the 968s capacity does have a ceiling. They do run out of capacity around 330rwkw ( or they have on my cars) so it was dekas or drilled. That is another debate however Link to comment Share on other sites More sharing options...

Fat-Tony Member 5,364 Member For: 18y 10m 3d Posted 07/05/08 10:04 AM Share Posted 07/05/08 10:04 AM (edited) Yeah well to add further to my experience I found that the drilled items yielded very poor cold starts. Funny that having spoken to a few people who have run these injectors, some who have removed them like I have had the same issues as me. All I can say is from what I have seen they do not do the job well. Having had a look inside a intake port of a head that was fitted with drilled items shows a rather odd spray pattern. Ohhh and to further add to this, although my car might run a tune from a different tuner, I had experienced the cold start issues with my Nizpro tunes also. Having the car stall for no reason during cold start was just one of the lovely issues me and others have had. Retuned the car and still had issues, changed injectors and nothing else but the scalers and viola, problems solved. I am not saying this to start an argument but just giving my experience with drilled items. I would welcome some comment/reasoning with regards to the above 2 posts I made. Perhaps I had a sh*t set of injectors. Either way I would rather use the cheaper item produced by a large company that has many engineers working for them designing things like this.

But that's still the same as all my previous cars have done doing the same thing & they have been slower. I have siemens sitting at home waiting for funds.PS isn't it commonsense that a bigger injector is going to be more difficult to tune as accurately as a smaller one.I get what Paul is saying though why take a rocket launcher into a house raid. Sure it can do the job but perhaps theres a more suitable choice of weapon that is more applicable to some situations. Link to comment Share on other sites More sharing options...
