A dyno day would be of interest at some point for me too, and with the changes you are making hourly it seems Robo, a dyno pull would be of interest for your Sky
Hey! I have a goal and once I reach it this will stop...
I was under my car to do the diffuser this weekend and found out my exhaust is loose. That's never any good for tuning or running. It's not like hanging off the car but either the bolts we used stretched or something because while they're tight, the exhaust can be moved around considerably and easily. Uhg.
My concern was if I tried to remove the bolts holding the exhaust on and replace them, I could snap one off in the cat (been there, done that) and, at that point, I would need to take the cat off completely to get it out and replaced. At that point, if I'm doing all that, I'd rather be putting a High flow in. Ergo the new cat. Though that may even go in before the Mod Day depending on when I get it and how much it makes me mental knowing it's like that.
I will be available for all three of those weekends but I may have just messed up my next autocross run as I am planning for a trip to the UK for my Dad's birthday, which is on Sept 17th. I guess I should have booked him on a flight to come out and yell "you suck! Get of the track!" as I try and beat Robo's lap time (always 5 seconds faster than me). So much for getting my DDM braces ordered and fitted before the next autocross run, which I guess it still will be if I wont be racing till October
I say your tires are at least 2 seconds of that. Yes, your braces will be here before your next autocross but you should have checked the calendar. LOL
On an unrelated note, I just got my Sky smog checked yesterday (first time since purchasing) and she passed with flying colors. I mention this because I didnt know how a smog check would go in California after having the Trifecta tune in place. I let the smog check occur with Trifecta enabled. So if anyone ever has this concern, with a stock Redline, Trifecta does not impact certification (if other parts were in place, like CAI etc. it could be a different story). Some discussion I had a while back (on either this forum or in person, I dont recall) raised concern as to how it may affect emissions but no impact experienced. I love my Trifecta tune !
Did they put it on the roller? My understanding is that now all you need to do to pass smog is to pass the diagnostic check and visual. I was told the roller check is no longer necessary. If you have the GMPP intake you would have no issues too since it has a CARB number. Cat back exhaust wouldn't affect it either.
Anything without a CARB number is a POTENTIAL problem. I imagine though if you put on an aftermarket Turbo and it LOOKED factory (and had no engine codes) you would be fine. Same with getting aftermarket charge pipes that were natural or flat black finish, injectors, intercoolers that didn't scream "I'M NOT STOCK" (like, having the manufacturer's name painted and visible across the front of it), and engine internals like valve springs, pistons, rods, head work, etc. Swapping out your factory cat for a high flow would be fairly obvious (they look nothing alike and the high flow looks aftermarket because it's not big, bulky and ugly) as would anything using AN fittings or powder coated parts. (I know, seems silly but I've seen cars fail visual because they had factory OEM parts powder coated on the engine.)
I felt the Trifecta tune would pass smog even under the roller test since my HIGHLY modified Grand Prix would pass the roller test no problem (big cam, huge injectors, 18 psi of boost from an aftermarket supercharger, ported and polished heads with heavier springs and bigger valves, 160* t-stat, colder plugs, headers...which ironically were the only CARB legal part on the car..., etc etc etc)
