I recently had a manual conversion done to my r34 gt-t and it seems to me that it is drinking far much more petrol than when it was an auto and also it is much much slower than the auto now. I am still using the factory ecu by the way. Would it be a matter of just purchasing an afm ecu like the power fc or is there much more or less more to it than that? And the TCS seems to be very sensitive now, for when i Pass the smallest of bumps SLIP comes on and cuts my fuel and thus i lose power.
Any advice will be appreciated.
Thanks
