DeatschWerks is an Oklahoma-based manufacturer specializing in high-flow fuel injectors and fuel pumps for performance and forced induction applications — the fuelling hardware that supports power levels beyond what factory components can safely deliver. Their DW300, DW400, and DW65C in-tank fuel pumps are among the most popular performance fuel pump upgrades in the sport compact and turbocharged performance community. At MyPartsGuy.ca we carry the DeatschWerks lineup, all priced in Canadian dollars with no import fees or brokerage charges.
For Canadian enthusiasts building beyond Stage 2 power levels on any turbocharged platform, upgraded fuel injectors and a high-flow fuel pump are not optional modifications — they are supporting requirements for safe fuelling at elevated power. DeatschWerks provides matched injector and pump solutions for most popular platforms.

Frequently Asked Questions
When do I need upgraded fuel injectors?
As a guideline, when your power targets require your injectors to operate above 80–85% duty cycle, upgraded injectors are needed to maintain adequate fuel delivery headroom. For most turbocharged sport compacts, this occurs around 350–400 whp depending on the platform. A proper fuel system tune will tell you your current injector duty cycle — if it's above 80% at your target power level, injector upgrades are the next step.
Do DeatschWerks injectors require tuning?
Yes — any injector change requires a tune to correct injector scaling in the ECU. Do not install larger injectors without scheduling a tune — the engine will run lean or rich depending on how the ECU compensates without updated injector data.
