hi everyone, i did a quick search and couldn't find what i need. here's the story:

i bought a used comptech supercharger kit with aftercooler. it's been installed, with headers, exhaust, and throttle body on the car. once the install was complete, took out for a test run and it made no power, lots of black smoke, really loud backfire, and shot flames. after that, i got a fuel pressure gauge, and it read 38 psi, so i bumped it up to 45. it runs a little bit better, but not great. this is a bolt on kit, and it should run fine stock, with no tune, and that's all i want right now. any ideas how to make this run better?

it came with an esm box which i was told was only used for high boost so i didn't install it. should that be installed?

thanks everyone

 

The ESM needs to be hooked up, it tricks the ECU from seeing boost. As far as I know, you should not run the kit without the ESM hooked up (unless you are running K-Pro, AEM, etc. for engine management).

 

thank you, i will hook that up asap. should that fix the problem?

 

Yes.

How your car even started without one is baffling enough.

 

I am by no means an expert, but did have a SC'd AP1 for quite a few years. I had one of the wires from the ESM come loose and the car would barely run. So I would say yes that should fix your problem.

 

lol, thanks everyone. you've all been great help.
