When people say "pop", they mean like a balloon. You could blow the seals if the engine detonates before you upgrade the fuel delivery and ECU. Then you'll need a $3000 engine rebuild. The engine detonates when boost goes up and the fuel:air ratio doesn't go up. An aftermarket ECU let's you manually adjust the fuel:air ratio, assuming your injectors are large enough to handle that much fuel.

i run the haltech e6k, if i were going to do it again with a low horespower goal i would go distributor with a sds or even an additional injector controller. you can make good power that way and not spend money, my friend here in texas ran 10.55 on an sds and a distributor from a 12a. do more reading, its lots of fun to go fast but only if you go fast without blowing **** up. i wish you the best of luck, check the haltech website and read and learn, you can pick up an e6k with sensors for around 500 bux.
