you dont get fine adjustment fuel control with a vpc...they only let you take out X% of fuel from the whole rpm band...you need some kind of additional fuel controller (afc or gcc or afr) to get good control.stoker6 said:Go MAP from MAF. MAP ECU or VPC or standalone (AEM, Motech) Get fine adjustment fuel control if you go with the VPC.
Get a 4in air intake. Tune to 11.5:1 AFR from 4krpm to redline.
Get 100 octane or better and turn up the boost.
