Default Injector and Fuel Plate ?

i have talked to alot of people about this some enthusists and some techs but some say do a fuel plate first and then others say do injectors first. the techs say if i do the fuel plate first the injectors wont atomise all of the fuel and will blow the tips of the injectors, but if i do injectors first the pump wont handle the excess fuel because of the stock fuel plate. anything helps thanks guys

stock pump on these trucks will hold anything just cut your stock the fuel plate to a zero and add your injectors. and get some gauges to.

yup. gauges are number one on the list, atleast boost and EGT, and tranny temp would be next in my book..... then later on down the road a fuel pressure gauge....

i ran for over 4 years after doing the plate and before doing injectors and never once had a problem with the tips on my injectors......

yeah those injectors will be fine just cut your plate to what ever you want i suggest a *100 but gauges gauges gauges got to keep an eye on your egts and boost dont go over 1500 degrees for more than a few seconds and with a stock charger try not to go past 35 pounds they will handle alot more but after 35 pounds they just make pressure and hot air they are way out of there efficiency curve.

Just save the money cut your own #100 and get some mild sticks. DONT worry about hurting anything by putting in injectors and having a stock plate.

I did 379rwhp with a 5 plate, afc mods, 60hp injectors, and 15* of timing.

your number should be very easy to get with you 181 dv's over my 131's.
