4. I don't know yet... had to leave town before I could get a log to them.

Could under hood heat soak be causing sensors to freak out?

I thought LJ's 300hp pump gas tune was setup for the 550cc injectors that normally come with the kit? I would make sure you are running on a tune for the 1000cc injectors. My guess would be the BOV opening slightly at idle and high vacuum conditions causing turbulance going across the MAF. This is easy to notice. Just watch the valve on the BOV at idle and if you see it move at all then you need a stiffer spring. I am running the 11 psi spring with a couple washers. I think the correct spring is the new 12 psi spring.

What spring are you running now?

It is only a basemap, and I agree that everyone should get a proper tune. I would make sure you get a boost gauge and AFR gauge asap though to make sure whatever tune you are running is running properly without having to datalog with EcuTek.

If memory serves, I think it's a 9 or 10 lb spring and the valve connected directly to the manifold. Still doesn't solve the flutter, but it's a bit better. I don't like how late the valve actually opens. It's a good 2-3 second delay between taking my foot off the gas to the valve actually opening (not just the surge / flutter noise)

Thanks everyone for the good responses! Hopefully one of your suggestions solves this problem! I have a lot to look at when I get back home and since it will be December by then, I will have all winter to track the problem down before driving the car again.

re-tune ur car , do u have any black smoke ? can u use laptop and check the old tune

Jesse, we were suppose to link up remotely to do some logging/adjustments. The 1000cc tunes will need to be touched up to make sure everything is fine.

When you get back into town, please give us a call and we will sort those problems out Free of charge.

Let's hope this doesn't turn out to be like the FRS300 fiasco. Bad install/wrong_calibration leading to engine failure leading to 6 month+ $5k+ engine build at another tuner still waiting to happen.

Do we know for sure it was partially the tune?

No, of course not. 'We', as in internet forumites, know nothing about the actual cause, but this is a bulletin board and the modus operandi is to speculate.

It very well could if he doesn't have anyway to monitor how the engine is performing. Please make installing a boost and AFR gauge the first thing to be done.

It kill me when I see FI cars without boost AFR gauges. I bought my gauges 2 months before I went FI.

Sorry I haven't replied to this in awhile... I was finally home long enough to work on the car. I data logged and found out it was loosing fuel pressure while idling for awhile. It turned out to be nothing but a bad fuel pump. FBM sent me a new pump and 20 minutes later the car was fine!
