I went ahead and ceramic coated everything on the engine, headwrapped the DP, BIG ASS rad and intercooler.

I dunno man, I think that's a little bit of a stretch. My engine runs 173ish*'s all day long and I warped 2 seals pretty damn quick. I would like to know what the egt difference is between 13 and 13.5

I have focused on this on my new motor all except the coolant passage way milling(most important..wish i would have). I will say my temps under the hood with my heat shielding, ceramic coating, exhst wrap and fresh air ducting and UIM and LIM coating have been impressive BUT until full boost my observations are just that...observations, nothing concrete or substantial til then.

Do you know what he's running for a turbo? I've seen an A-Spec 500R kit do damn close to 500 with a little windshield washer fluid injection

I like Aux injection, with the exception of two points.
1) No-One can definately speak about the wear that the injection causes by washing the oil off the housings etc etc
2) I have yet to see one kit that is fail proof. I am not completely up to date with Howards setup, but I am with BDC's..... now... you're using this piggyback system to inject whatever, and if you look at the fuel maps, you're pulling fuel, and ALOT of it out as soon as the boost comes on hard. Now, if ANYTHING goes wrong with the aux injection, it seems to me that it would cost you and engine right then and there. I'd gladly rock an aux system if I could run it off the Motec and have a few failsafes.
