Flash Sale! Starting right now through this Monday only, we are offering the Xtreme-DI LF$ HPFP Assembly for $250 off! This brings the price down to $749.25 😉 This is the first time we’ve ever listed this item on sale, and it’s our best deal ever!

These are brand new AC Delco Delco HPFP assemblies that have their internal pistons replaced with AutoTech internals (11.66 mm. diameter). Then the unit is assembled, flow tested and broken in on Xtreme-DI’s in-house HPFP assembly test bench. The Xtreme-DI HPFP assembly increases flow capacity by 36% over stock. When used in conjunction with the Tapout fuel cam, flow capacity is increased by 64%!

This saves you a step by not having to install the AutoTech HPFP internals yourself, so you can get racing sooner!

After great anticipation we are happy to announce that E01 Global B Remote Tuning for the Cadillac CT4-V 2.7L is now available!

We spent the last several months working with HP Tuners to figure out E01 tuning.  As it turns out, a new torque model concept is used in this controller, which is very complex, and at this time there is no means to properly generate new model data for it.  However, we were eventually able to find a solution around this obstacle.  This was the most challenging tune we have ever done.  Dozens of new VCM Editor tables needed to be defined, and many new VCM Scanner PIDs were added as well.

All the extra time and effort proved to be worthwhile.  We picked up more than 40 whp and 50 wtq throughout most of the powerband.  Then we had Brian from Brut4l Ass Kicking calculate the optimal shift points so we could program the TCM accordingly.  0 to 60 times have now improved from 4.8 to 3.8 seconds, making this car launch as hard as a CT4-V Blackwing!  These numbers were all on 91-octane fuel with no mods.  There should be even more gains with 93-octane. So, whether you’re looking to Remote Tune your CT4-V with HP Tuners or bring it straight to our shop, we’ve got you covered!
