I'm sure you're aware of this already, but wanted to throw it out there anyway. Even with a cooler stat, you'll still run close to the same temp that you run now at city speeds. Your PCM will need to be modified to lower the fan on-temps to take advantage of this. At highway speeds, you should notice it running cooler.

12.8* of timing isn't the cause of the lack of power though. When I dyno tuned my truck, the power pulls I made at the end of the day were with 150* IATs, 230* ECTs, 11-13* of timing and power was still over 400hp with the stock cam. Fuel is good, spark isn't horrible (assuming it's correct), there is something else going on. Not a big deal as long as they're gapped around .035" with the stock coil dwell times. With longer dwells, can increase that a bit.

Something to that effect is what I was thinking. Quite simpler than that, did you perform a crank relearn (perhaps using Steve's EFILive) when you installed the tuned PCM? Could accidentally over-torqued rockers be an issue? Would be very easy for you to re-check them... 22 ft-lbs is all they need

09 CTS-V will definitely be added to our garage. Come on ebay, let's see that stock, go up.

Exactly why I tune by mail the way that I do. All too often, there are mechanical variances that result in a tune that does not work well in one vehicle but works very well in others.

Only have one photo that I can think of, and it's not a very good one: Wife's 9mm Custom Shop Sig 226. We've also got... Springfield XD .40 Remington 870 Express Remington 870 Wingmaster Mossberg 590 A1 Western Field .410 Marling 983 .22 Win. Mag Soon to add H&K USP and a rifle or two

My wife and I both have the blackjack. It's a great phone. Only complaint I have is with the oversize battery they provide (comes with two). Battery life is unpredictable with it. It'll show 3 or 4 bars of power for a few days, then go from 2 bars to completely dead in a matter of a couple of hours. Problem doesn't seem to be there with the smaller battery.

As I recall, it's legal to have a pistol grip on a pump-action shotgun, but not on a semi auto. Justin

He's got one of my scan cables right now

Definitely. Once I have the times locked down, I'll let you know. Justin

High impedence. Check out racetronix as well./ http://www.racetronix.com/

According to GMPartsDirect, the 8.1L injector is #12574927.

Nope, none yet. Just set the date for it yesterday. Justin

I'm going to try and tack on another day to the next EFILive course, which will be Dec 1, I believe, so spending the day at the dyno on Dec 2...

I did the dyno tuning of it (spark tuning) in Temecula. I'll be back there and have some available dyno spots in a couple of months.

Damn Chase, that sucks.

Don't forget the dyno time

Yep, I'd recommend Kushan @ Excelsior as well. He's a good guy. Scott Brown at VBDyno.com would be a good choice as well. What are your goals?

Definitely a fun car there. Now, if only your truck was on the rollers, that would have been a good time. Maybe next time. After seeing the correction factor for the weather, I contacted the 383 tahoe owner and gave him the new numbers. He recalculated the d/a there and, assuming 24% driveline loss, his 383 gained 33hp over the assumed 345hp on the stock 5.7L tune.

They still use pounds in the UK. When I was over there in June, it was right at L0.90 for a liter of gas... L3.4 per gallon. Which works out to be just about the same as it costs in the US, we just get HOSED on the exchange rate.

Hey Art, Interested in wrapping a few pieces for me and my soon-to-be-wife? Bring that by the dyno next week so I can check it out.

How lean are we talking about here? Next step up from the stock radix injectors are the svo 42s. It's not a plug and play swap however, you'll need to have your PCM retuned for them.

Looking good Art. Too bad you guys aren't doing it next Sunday when I'll be down there.

Tune: Tuned myself Couldn't begin to count the number of 1-2 WOT shifts, but it's spent a full day tuning on the dyno, towed a heavy load across the country, has had a few near-WOT 4-3 downshifts at over 100mph. Have yet to feel it slip once.

Think I've had to log in 3 or 4 times today alone...
