Well as the title says i've came across a few drive ability issues as of late.

i got the car staged with my 2.9 and it ran great for the most part....now i've steped down to a BF 2.7

when i run the car out and take it to the awesome 7k redline thro 1st,2nd and into 3rd the car gets a little weird.

when i go to rev to down shift theres what seems like a lag but it harsh and sounds totaly differant then normal.

it doesnt thro a code all the time but when it does i get a p0103 code wich is a MAF sensor code.

this happens every time i drive it like that with the 2.7 and some times but not that offten with the 2.9

any ideas whats causeing this?...do i need to go to an even colder plug?...re-gap them?....

or is it finaly time for a ECU tune?????

never ran into this problum with the car before i got it staged flashed.

 

keepin the dream alive!....

 

hm here is a free *BUMP* token

 

still using the stock belt? it may be slipping.

 

nawwww....

stock belt yes but the tensioner has been replaced by a 78mm tensioner...its also a flat pully not groved so its a true 78mm.....

good idea tho.

from what i've been able to gather the answer is in the code...

p0103 is a MAF fault...to high freq so the ECU stops useing it to take incomeing air mesurements thus leading to a crapy runing car.

i just wanted to see what people on hear thought....a tune will fix things.

any body else got any ideas????

 

I don't own a SS/SC, but from what I've read on the forums, it seems like it's time for you to get an ECU tune. Seems dangerous to be running that much of a smaller pulley without a tune. Your mod list says you're running Stage 1 (GM stage 1?) injectors. You have a lot more air coming in from that pulley, are those injectors big enough?

 

ohhh sry bro...havent changed the sig yet....

i've got the stage tune and the 42lb injecters.

its all in an ECU tune so far...i was just checkin to see what people had to say.

 

interesting

 

Ah, ok. Sounds like you know what to do then!

 

it's karma for owning a black SS/SC.... when i wanted a black one :P

.... hmmm... i would guess you need a custom tune.... but you obviously have the same idea
