help for tuning a 90 must

[sircouture]

I have a 90 mustang an have pinging problems.and want to get it tuned the right way. I want to know if this would be a good setup for a 347 stroker

A shop proposed to intall 42# injectors with a 90mm lightning mass and a diablo mafia with the delta chip . Would this be the way to go to tune it perfectly.would 42# injectors be to big.

thanks

Is this motor N/A or blown?
If N/A, 42s will work, but there should be no need for a Mafia.
If blown, you may need the mafia, and i would think 60# injectors.
The lightning MAF is a great piece.

Thanks

I'M n/a but with nitrous planning to spray 150 to 200 .will 42# still be good.The shop that proposed to do the tuning is a shop that is specialized in turbos and blowers so that prabably why he said the mafia.
so with the 42# and the delta chip and lightning mass he will be able to tune it perfect.

Thanks for the help I'm happy to know I got good advise .I live in Quebec city Canada and tuners are rare around her and especially good ones.

so thanks again.
