No you are right...just need a 10mm wrench and pull off the black wire(negative) leave it off for about 10-20mins and then put it back on. Nice gains, with this car i believe in resetting the ecu with any mod that affects afr and things of that sort(even if it doesnt do anything i will still reset). Just wondering whats up with those weird dips in the graphs, regardless nice gains with the injen

I read this as better top end power but the low rpm power dip has gotten worse with a loss of about 10HP. Am i reading this right???

The rpm sensor on the dyno kept moving... That's why it diss connected on the graph, sorry for that:thumbdown:

ECU shud adapt eventually

Nice gains! Seems like it lost a little bit of power/tq in the lower rpm range though. I wonder if the ECU will compensate down the line and negate any gains?

The more i read about the Injen intake, the more i see impressive results.

How is the drive-ability with it? is idle alright, is it rough?

Seems like a really low baseline pull.... hmmm

This is encouraging me to grab an Injen and do some comparisons of my own.

I'm really intrigued at how low your car dynoed stock. My stock pull with ONLY an SRT HB exhaust was 174whp... but I also ran a full unit leaner too (like on your injen run). Take away the exhaust, which is advertised at 10whp and that puts me at 164whp stock... which is what your car ran with Injen.
@Bahraini86, any chance you could email your drf files so I could do a direct overlay in WinPEP?

Wow 10HP??? Could that be real? I mean when do you ever see 10HP from an intake. Especially, it's not even a CAI. Just wondering here...
