Major issues, The truck wont shift at full thorttle and is bogging. I currently have the stock plugs in which is a problem. Im going with ngk copper gapped at 035. I bought 38lb injectors. 4:1 fmu re cab,... My question is can i get away using a stock lighting 90MM MAF on my 97-f150? I got it dyno and the guy told me i should remove the cats also... Any help from you guys or ideas to get this running right. thanks

 

ummmmmmm, ditch the fmu , its useless and get the car tuned properly on the dyno with a custom program for your truck ! the fmu is so old school...................with a proper tune you will not have any fuel issues............use the lightning maf with the injectors you have. also youll have to have the tuner do the transmission shift points as well ........................
