I have just installed a new heads and cam, now the car dosen't shift at full throttle. It shifts fine otherwise and I have a madz28 tune.

Is it the tune or the tranny?

Thanks
Joe

 

your not from me, about an 1/1/2 hours.

couple of questions first. have you contacted ion (madz28) about this yet if so what did he say.

did you install the gears after the tune, or did ion know about the gears and was that part of the tune.

you dont have a stall do you, if so how big.

and is your car obd1 or obd2.

 

I haven't contacted Ion, yet.
He knew about the gears with the tune. ( the mph are fine).
I don't have a higher stall converter, yet.
And, it is an OBD2 computer.
I actually live in Keller, Texas.

Hope this helps

Joe
