Tip In Stumble?

[BoostedBug]

Right off Idle there is the slightest tip in stumble..IAC and TPS are perfect, o2 and MAF are also.. Fresh motor with a good bit of work done to it...Just trying to figure out the off Idle stumble...

A lot of cars have experienced that. Mine did untill I had a new chip burned. Good Luck.

That is what is wierd..It did it with my Red 107 chip and now it still does it with the new Turbo Tweak 93 chip..

 

[WHEEZER]

That is weird, TT normally eliminates everones tip-in, to my knowledge.

TPS is set at .44 and 4.86wot and IAC is at 35.

Fuel Pressure is a little low at 40lbs on these 72lb injectors..I think I might turn it up to 43 lbs and see how it does then...

 

[WHEEZER]

Could be worth a try. What pressure did Eric reccomend for the chip? I wonder in a worn throttle plate shaft would contribute to a tip in condition?

TPS should be set at .42 try that and see if it makes any differance.

Mine did that and Eric suggested turning the cam sensor in a little more, so that it's not riding on the edge of adjustment. Since I did that ,I have not had any stumbles off idle in 1-1/2 years. Good luck

I have that now with a bigger turbo, T70. That turbo has a few weird spots you need to just avoid. A BOV helped in a few spots, but still has tip in stumble, unless you go past "x" throttle position.

I have the 70 q trim also.....Wiht the NLU 9" in it is not that bad of a thing because the car does not jump out on you but it is a little annoying..

Tell me if you ever find a cure. On one street coming home every day, I have a place that makes my car go 2-3-2-3-2-3 shifting, if I drive the speed limit. Turbo surge. I have to either coast down the small hill, or give it more gas and accelorate then coast, etc.

Only happens on this road! Weird.

Set your IAC's in hot neutral @ 10-15. Should move to upper 30's to low 40's in gear. This might help. Brian
