well the CJM is now $995 (was $1299 6 months ago) which is nice because the kit IS better than the AAM kit - it's heavier duty and won't make your engine bay smell like fuel like the AAM seems to on some cars. Actually CJM also has a stage 2 kit out now - well maybe the stage kit was the original kit, then he took a couple items out and called it the stage 1 kit for $995, but it's still the best kit for under 550whp. I think his stage 2 kit goes up to 650whp. After that people should start looking into the $2000 APS fuel kit

Yeah, can't wait to get my 550 injectors in and start redlining the car

 

Sounds like you have the coil packs swapped around.

That is exactly what happened to me.

Try that.

 

Yes...never thought of that . Some thing to look into

 

Thank you so much guys... that what I checked just before you mensionned it and that was exactly my problem... I had a coil not doing is freaking job properly...!!! I appreciate so much all your help!!! my head was going crazy thinking about this issue every minutes of every days!!
Just to know, since I see some really nice number you're pulling, after adding headers, test pipes, catback exhaust, retuned the SplitSecond ECU & lightweight pulleys... what would be the best upgrade for gain/$ on the Vortech Kit?!?!?

 

Plenum spacer is a great mod NA or FI. My car showed an improvement of 18rwhp on the dyno at full operating temperature.
