[QUOTE="superpsd, post: 1545592, member: 15821"] Heres the thing though as far as better atomization. Due to the heui design there will be compromises. The faster you can actuate an injector the higher the pressure will be at the nozzle. This is where a hybrid shines at higher ICP. B codes take much more HPO to actuate the injector. The BI codes are split shots. I run BI codes but I tig welded the spill ports shut to covert them to a single shot and run 200% nozzles. They run very clean with dialing in tuning and fuel economy when daily driven is about the same as the truck when it was completely stock. B code springs are 3600psi VOP vs the A code 2750 psi. If I recall the numbers correctly. A higher VOP will create better atomization and drivability at the expense of lower power numbers up top. Or so some have found. A higher VOP also creates more initial delay which retards the SOI if you make no tuning changes as the actual PW will be shorter with the same commanded PW due to mechanical delay. [/QUOTE]
