hey guys finally got all the parts installed on the car :
- Aero force scan gauge
- boost gauge ( getting 8psi on 3.4 Pulley)
- headers. 3 inch down
- thermstate 180
- AL 104's gapped at 52.
- overkill tune pcm
- 3.4 pulley
- cat back exhaust
- open cone K&N kilter 4 inch inlet.
- NGK wires.
- running on ultra 94 octane that i found in my city and rarly on 91 oct.
OKAY! now to start im getting rough 4-5*KR at WOT which isent too good. the power is there tho. and im also getting hesetation like a misfire only at WOT. what could this be wire new plugs new and all gapped corrrectly.
why am i having soo much KR? after putting on all the mods? an soo low of boost like 8 psi on 3.4 pulley isent right..
 


Did it begin happening after the new plugs and wires were installed? 8 psi on 3.4 seems ok to me, headers and exhaust will decrease boost due to less restriction..
 


The gtp's Overkill tune was rather too rich. Probably ~10.5afr wot. Saw plenty of KR (4-7*) at the top. Might be worthwhile to look into that.
 
downpipe dosent hit the sway bar at all. i heard some people had that issue. but i never had issues with that. illl change that coil pack and go from there...
 
i went to toronto yesturday to try and find will (overkill motorsports) shop and there was no luck. its like its unlocatable
 


I had sent you an email regarding that. Its a mailing only address, all you'd find is a UPS Store.

I'm certainly available for in-car tuning if you'd like me to have a closer look at the vehicle, we just need to make an appointment. I'm booking just over a week in advance at the moment (track season, busy).
