yeah when the car over boost's the car will knock if there is too much air (lean) so the ecu pulls timing or fuel to correct the problem. watch your gauges (a/f, boost) and get it tuned or at least a base run to see where your numbers are at........

 

you need a tune!!!

 

you need spark plugs not necessarily a tune

 

yeah i had the same problem the other night, and dont say" U need a tune" cuase i have a very nice tune. im thinking my problem is the plugs. i would suggest checking yours sometime.

....Yet. I drove my evo for about 3 months with turbo back and intake til I got fuel cut

 

....ohhhh ohh ooh yeah...

I agree.

 

tune it...

 

I second the people sayin spark plugs, its one very inexpensive thing to check first, yes you do need a tune as well though.

 

that happen to me, tune or maybe change your spark plugs

 

wow we have 15 noobs trying to answer

he's simply getting boost cut because of the weather. flashes disable it, quite simple to do if youself actually if u get ecuflash software

shuttlegoose.... its NOT too early on a stock 9. around the RPM u mentioned where u received boost cut is where it spikes. by top end you will be back down roughly 2-5 psi (depending on ur car).

 

ok thats what i was thinking, i will deff get a tune then, and change my plugs while im at it i guess, i got on it a little bit the other day and it didn't do it, maybe it was just because it was so cold out.

 

The Newbie title has nothing to do with the person behind the keyboard. We have a lot a people that have been on this site for years, but don't reply, start new threads or don't get in to the Forum atmosphere.
In the end, it's up to the OP to decide his next move, with the advise given.

 

I turned my boost down to 19lbs and this will have to do until I get a tune. I use to change plugs when I hit fuel cut but I got tired of spending $40 bucks on iridiums every 1200 miles.
