Car acting rough in boost... what do you think
The last week or so my car has kinda been acting rough in boost. The vacuum->boost transition seems rough, and the car seems like it is kind of pulsating in boost. It pulls just fine, no loss of power or anything. It just seems like extra vibration when boosting.
My EGTs are perfectly fine (never go above 700C or so when daily driving, I seldom wind out gears to redline), and my A/F (better than nothing) gauge reads far into the rich.
I am thinking that my missing link is clogged or something, what do you guys think?

at more than 4000rpm, slam on trottle suddenly, if the car jerk hard be4 boost up then probably the map sensor is bad.

Hmm, I do not know whether it is related... but my car has a loss of power when accelerating from idle. It is only when it is REALLY hot out, or I have the A/C on though. It feels like it is going to die at idle, I floor it and NOTHING. Then I keep it floored, turbo spools, wheels break loose. It's really funny.
I was also thinking perhaps it was ignition related? But I dunno.

Does the car have gas? LOL.. (dont laugh.. hustler ran out of gas twice, same spot, and this nice GSR driver gave him a ride to get some both times..)... his was hesitating and sputtering similar to what you describe (even though it's on a supercharged mudstain..

Fuel filter could be clogged, it only takes one bad batch of gas to screw it all up. Or maybe even water in your tank. Try some fuel additive and a new fuel filter, this sounds like a similar problem my friend was having.

I do not think I even have my check valves anymore. I gave them to some guy who wrecked his car the next week.

That's the same thing that happen to me, it starts out only when a/c is on, then it happens even when not on. if you have an extra map sensor(i think drag3 come with extra map), try it on, my car runs fine after i changed my map.
