Actually I'm in Glendale ...

I'm getting my APS Up-pipe (and Big Brakes, Hotchkis sway bars, Tein springs, pressure gauge) installed at Suby Specialties (close by in Monrovia) next week.

I already have a down-pipe back Stromung exhaust, K&N filter, pulled the silencer, STI hood scoop.

I think I want the ECUTEC management system ...

Should I have Suby Specialties do it .... or is it worth it to have GT Motorsports do it on their dyno ... ?

I do use a 94+ octane fuel mixture ... so do I need to do a dyno tune to take full advantage of that?

Or is it really worth it to bite the bullet and go up to Vishnu? We can't seem to get Shav down here for a group tune ... :-(

Or is the chip that Shav mails to you O.K.?

if you use an off the shelf map (which at your level of mods you should) There is no reason you shouldnt do it yourself. Swapping the ECu takes all of 10 min with like 3 basic hand tools
