Did you keep the stock injectors? Stock spark plugs or colder? Are you runnig an FMU?

CMW

No... Larger injectors are part of the package. Sparks are single platnum (Bosch). No FMU although Mike and I were talking about that Supershark program thingy... (I haven't actually read the posts).

hey chris, have you posted a dyno? im really interested in what happens to the power and tourque curves in the upper rpm range. is your GTS auto or manual?

I see, sounds like a good package. In the boosted world the consensus is to run copper core plugs at least one range colder. I’ve read and heard many problems relating to platinum plugs in boosted engine. Swapping my Bosch Platinums to HGK Copper core plugs was the very firt thing after I got the SC buttoned up. I’m guessing you had good luck with the platinums so far, but it might be a good idea to keep this in mind in case the engine develops ignition issues in the future.

No problems with the Bosch... we needed to avoid Plat 2 and Plat 4's.
Also I hit send before I meant to... there is a Bell FMU/ RRFPR (not sure which model).
Yes I understand the need for cooler plugs... they may be regular Bosch?
I know they are not HGK's.
Might be worth a swap in the future to see what it does. However no problems with the plugs I currently have.

Andy didn't recommend platinumr plugs and wanted one range cooler to be used than stock. For the GT this was the WR7DC
