I have the EBL Flash 2 system installed on my 91 S10. 4.3 .30 forged internals. S257sx-e. 33 lb hr injectors (wired in parallel. 3inj per bank 2 banks. Vacuum and boost reference afpr. (2 bar map installed and option word checked)Got the truck started up, and most tuned in. The thing is, it runs fine until the map hits 100kpa. If i remove the bov and keep it from hitting boost all is fine. Once it hits 100 kpa it drops 2 cylinders. (New cap rotor(msd)plugs (delco rapid fire part #1) wires (msd 8mm) and msd coil). All boost settings are the stock settings for a 4.3 as delivered in the bin file. Where should I start looking? v40a xdf
