i have a 2000 silverado with a 5.3 and a procharger,,i want to ditch the fmu....what do i need to change and does anyone around clearwater fl. tune?
thanks in advance..

 

If I am not mistaken you with have to put in some larger injectors ie(43lb or bigger) and naturally change the tune to match the larger injectors. Your injector flow rate table will have to be changed as well as whatever else you would like. No sure how procharger does the tuning side of it.

 

Im in the same situation you are. I'll be putting in 42 lb. injectors and getting a tune from nelson. Alan told me to put in 42 lb. inj. and keep the inline pump, then I can ditch the FMU. I'll probably get HP Tuners also, That way he can change my tune for me through e-mail and just load it from my laptop.
