Customizable DSP5 ECM (you pick all/any tunes)

example: 285/75R16

Transgo Jr. is not considered a built trans. Please select No above

This part takes 5 minutes to install and will allow your truck quicker spool up, cleaner operation, and 5-6 more lbs of boost under full load (~31 psi peak). For stock or built trans LB7 ONLY.

Solves most P1093 and P0087 codes. GM's fuel pressure relief valve is notorious for opening under hard load and dumping fuel rail pressure. 30 minute install, instructions and replacement valve included.

This part can be easily installed to keep exhaust gas from recirculating to the intake manifold. Installation results in higher boost, improved efficiency, less smoke output, and quicker spool-up. This part is for off highway use only.
