Running big boost and want to maximize your control? Meet the Turbosmart e-BoostHP, a self-contained electronic boost controller capable of handling up to 120 psi of boost. It can also control water spray, methanol or nitrous injection, manage shift/warning lights, and read/monitor RPM. That’s twice the maximum boost capacity of the e-Boost2’s 60 psi max. With so many boost-hungry enthusiasts running E85 ethanol that 60 psi is well within the realm of possibility, so Turbosmart stepped up and doubled its peak performance.

All Turbosmart e-Boost controllers feature an exclusive adjustable gate pressure feature which improves turbo response by up to 1,000 rpm earlier in the rev range. This means users can increase the performance and response from engines without even raising the maximum boost level. Turbosmart’s e-Boost controllers also allow the user to control three different aspects of the boost curve: the maximum boost pressure (set point), spool-up rate of the turbocharger (gate pressure), and the reaction time of the controller (sensitivity).

The tuning prowess of the e-BoostHP was recognized at SEMA 2015 as the runner-up in the highly-contested Best New Performance/Street Product category.
