Ok, I have ordered the SVO 30# injectors and I'll install them soon as I get them. I was set to get Dyno Tuned, but I figured I'll do injectors first do it all at once. So I want to know is all this can be done this way rather than using MAFT? I think so but want to make sure. This stuff is all confusing for me and dont know what I'm lookin at when I see a trend as posted here for the injector install by anothere Teammate. By the way the T stat mod works fine just have to have fans reset. Thanks

Yes it is best to first install the new injectors then start engine,
let engine warm up to normal and let idle for a good 5 minutes so PCM can relearn idle using new injectors.
Then driver the car for about 1 hour so PCM will relearn and re-cal for injectors using different engine loads.

After that the PCM tune should be done for PCM will have by then averaged out for new injectors.

Dyno tune is a waste of time for your ONLY seeing the few conditions and fuel trims used on a dyno which is nowhere near real world driving where all engine conditions, shifting, A/C, etc are used and PCM is adjusting for all of them not just the 20 seconds on a dyno with no idle, shifting lifting of gas pedal etc.

Using a PCM scanner recording while doing the different driving conditions/loads and then using that recorded data will get you a much better overall tune then a dyno will and how I haved tuned close to 200 cars

Most teammates prefer to use our Team ZR-1 email system rather then the forum, thus I do not check it every day.

I agree real world drive that thing, and if you budget allows pick up a wide band O2 system. Your tuning will never be easier
