I am still waiting for delivery of the 185mm Pulley & Iridium Plugs.
I will get the ECU tuned - Just not sure by whom. I may go with a local shop in the SF Valley that has dyno. I plan on keeping my A/F ratios in the safe zone rather then chase peak HP. Not that I don't have big plans if I ever grenade the engine - but I just paid for the XF so I figure I should enjoy it for a while.
I am sure when I get the pulley, plugs and tune done - It will be fast.
I already have wings so I guess my next need would be an orbital re-entry proccessor.

Re-Entry processor...and some high heat ceramic tiles (preferably the kind that dont fail while flying over my house in TX).
Keep us posted - I haven't bought pulleys yet, and I'm anxious to see how the larger LET does on these cars as far as air/fuel. I'm also curious to see if the fuel system is at its limit with that pulley. I wonder how much the fuel system can handle?
Unfortunately, when I got my Y-Pipe it was the Pipe only - no inlet tubes. So, I'd have to buy the whole thing if I wanted to swap.
