Bought the upgrade jeep injectors, throttle response 80% better, also gained 2 mpg. Glad I listened to the forums. These guys are in sanford florida, I messed up an o-ring putting them in and called them, they overnighted new orings.
Would recomend them always, ordering a set of their high flow LS1 decapped injectors for my 5.3 swap next week.
Purchased upgrade injectors for a 2001 jeep wrangler, company promised better throttle response smoother idle. recieved the injectors and installed them. Hot start problem ever since, flooded engine, runs very rough for a few seconds after cranking over for 15 to 30 seconds. Found three of the injectors leaking fuel into the engine after engine is turned off. re-installed original injectors and the problem is gone. Precision auto injectors relplaced the faulty injectors. replacement injectors are doing the same thing. This time four are leaking, injectors look poorly assembled also. Emailed the company to return the injectors for a refund. they do not respond. checked online on multiple jeep forums, off road forums and other automotive forums and found many other people with the same problems, and some much worse resulting in permanent engine damage or engine failure from this companys injectors. I do not recommend buying products from this company at all.
