Funny I said the same thing about the 550 map and not washing out the cylinders via pm to him. Sounds like we're all on the same page here... holy sh*t that's scary.

that 550cc map would put you pretty close under vacuum and in no way rich enough to wash the cylinders.

Did you notice the symptoms driving over to the shop that the tuner is talking about?

The VTC can make a racket for a few seconds after startup. Who knows if that's what he heard.

Go back to stock ECU would be 1st step. Car should fire right up and idle nice and smooth. If it doesnt, you need to check fuel pressure.

Do you have the UTEC properly grounded?

I believe i have it grounded correctly i have the black wire coming from the small white pin connector going to a mount that previously held my stock ecu i have it connected with an eylet around a bolt. The red wire (the only other wire in this connector) i do not have connected to anything as i think this is not needed. is this correct???

check coils 4 and 6(driverside back two coils) the leads are long enough to switch them and i have seen it happen a few times. 4 plugs will look good and those 2 will be drenched in fuel.

As far as the utec im sure you can get it to run pretty good but will 600cc injectors at idle and cruising it will be tough to get perfect..
