Took the S out today for a spin as the weather was finally decent. I still could not get past 7500 rpms. New coils and spark plugs... It seems if I'm not getting on it I can get up to red line but if I floor it, the car won't go past 7500. To make matter worse something is going on with my meth kit now. It all sudden started spraying and wouldn't stop even with the car and switch off. I ended up cutting the power wire to stop it. I came back to reconnect the wire a few hours later and as soon as the two wires touched it started spraying agin. I have no idea what the problem is or where I should start. Any ideas or advice would be great.

 

sounds like you have multiple issues going. I'd ignore the meth for now and find out why it won't rev out first, mess with the meth later. what are you using to tune the motor? doesn't it run fine up until 7500 then the power cuts or is it sputtering up until that point?

 

I have an aem ems. It runs fine up until 7500. Powers there, everything's perfect until 7500. Again, I don't have the problem unless I'm flooring it. Since the car is tuned to have the meth running, I wanted to have that problem solved.

 

What kind of kit are you running, it could be you are possibly having a slight boost creep there and your tuner had set your ecu to shut off if it creeped to a certain psi? what is your boost gauge reading?

 

that's what I had thought the issue was. The car was tuned at 23psi not sure what the boost cut of was set at if at all. I turned the boost down to 16psi and I was still have the same issue.

 

Back to the tuner you go..........

 

man that sucks. hopefully you get it all straightened out.

 

i really don't want to have to pay someone a ton of money to try and figure out what the issue is.

 

is it breaking up or is it hitting a limiter?

 

feels like its hitting a limiter.

Does anyone think this could be caused by the battery relocation? This all started happening after my relocation. Not sure if one has to do with the other.
