Q: Stock MAF limits & injector size? - Series VI

[naych281]

Will I peg my stock MAF over 540rwh? Also does anyone else use sieman Dekas 60 lbs injectors $250 ?It seems my tuner can't tune my car without upgrading to injector dynamics $1000 because all other injectors does not give flow charts. Any input would be appreciated. Don't know if he is trying to upsell products..
Things I have installed and waiting to get it tune:

1. Kooks long tube with catted x pipe
2. Livernois stage 2 blower cam ( .221/ .228 with 113 lobe separation )
3. Colder plugs gap at .34
4. Alfco heat exchanger with dual fan
5. Mosleen belt slip system
6. 12" crank pulley
7. 60lb siemans Dekas injectors

Depends on what size your maf housing is. I was close to pegging with my 100mm Techco intake and stock maf at 640rwhp. I was using 60lb injectors too so I don't see any reason why your tuner is having an issue with them. I would also consider reducing gap on spark plugs to .032 or .030. And I am hoping that your crank pulley size is a typo cause 12" is like twice the size of stock :)

Seely,
My housing is stock extreme housing. As far as injectors go tuner said my injectors don't have flow charts like those expensive injector dynamics. But I already order sct ba5000 maf so we should be good. Also crank pulley is 12% not 12'... Also with my stage 2 cams I am disappointed that I can't even hear the loping sound at all. Grind specs are above. What do U think?

Maybe he is lazy. Of course he likes the IDs better. They are a better injector, but not necessary. There are plenty of tuners that can tune with 60lb injectors. I have used Lito for my car to remote tune and he is spot on and very easy to work with. I don't know much about cams. I am running Comp Cams 127300s and get a nice lope. Not too crazy.

I thought you were running Livernois per your original post. I will try and upload a sound clip in the next couple days. Probably won't be able to do it tonight.

Livernois uses competition cams and custom grinds them( according to shop )...
But thanks for all the help and info.
