First off, thanks for looking..

My car is a 2005 SRT-4

my mods are:

2.5" catless DP
2.5" Magnaflow DP back exhaust
Kinetic WGA
AEM CAI

I dyno'd at 238 WHP with a 9.8:1 - 10.0:1 AFR... any idea why i would be running so rich?

Also, my car keeps falling then spiking the whole way... have a look at my dyno sheet:





If some of you guys could give me advice, solutions or a reason why my cars doing this, i would really appreciate it!

Thanks in advance

*boost leaks?

about 2 months ago i was driving and boosting at about 5 PSI and i through a code... it was ''Major boost leak" the car bogged for a sec but then it was fine... i erased the code, it hasn't come back and i haven't thought anything of it..

So what do you guys recommend i do for the running rich? is there any way i can do tuning without buying a stage 1? would buying a stage 1 help in giving it a more accurate tune?

If you are running that rich on stage 0 bring up the boost a couple of pounds on the WGA and see if it leans it out a little. If not you need to either get a mapclamp or some sort of fuel control like a Dtec or SAFCII

boost leak does NOT make u run rich...it would make you run LEAN

If i have a boost leak then why is my boost holding at 15-16 PSI?

It stays right between 15-16 from when i floor it to redline

I'm thinkin more along the lines of plugs/wires in this case

i would also check for bad gas. because the dyno graph looks like he is detonting all the way to redline.

I'd like to see more complete information about the dyno and the actual runs. Those pics don't really tell much of anything other than a possible lack of smoothing.

when i had my HKS it got stuck open so it was leakin and i was still boosting 16psi which was normal for me back then i noticed cause of the power loss that i felt...
