As expected, stock injectors won't feel quite the wow that larger injectors will - but you will feel it and when towing you will wonder how you did without it. Larger injectors are the big winners with higher volume high pressure oil. The bigger the injector - the more power gains. Every injector size realizes fuel mileage. But make no mistake, this is not some small increase meant for small injectors. As common sense dictates and as our testimonials show, the larger the injectors the more power you realize from adding higher volume high pressure oil. This pump was made for any injector except B-codes and it will deliver fuel economy, performance and power to any vehicle. If you've been told you have a weak pump and are seeing a 1211 codes then we'll help you diagnose your needs before you spend your money on a pump. Programming can be the culprit for a 1211 code being thrown especially with stock injectors. Programming has changed over the last few years and you may just need some tweaking. The weak pump epidemic caused by bad or older programming has too many of you looking for a cheap pump fix. We'll try and help you fix your issues, but realize that it may not be a pump that you need. In this economy we don't want your money if our pump won't be your fix.
