Ok I finally got my car tuned from a local fellow who people say could do it. Now as stated before I am from the Bahamas so dynos are virtually non -existent. My car is a 95 gts-t with the following mods pod filter, fmic ,3.5" turbo back exhaust split dump, ebc 12 psi, 255l/hr fuel pump, .7mm gapped plugs , stage three clutch and afc neo. Now here is the question I have for you guys I was wondering if the tune I got was any good. When I look at the settings PER RPM on the neo everything is in the negative for both the high and low throttle positions. He has the low throttle at 30% and the high throttle at 70% now he did road tune the car with a buddy of his and he hooked up a wide band o2 sensor that he has as i dont have one. When i got the car back i must say it is very lively and i can feel the difference in power i can feel alot more pull under hard acceleration when on boost. I have opened her up a few times since then and have not heard any knock or feel any missfires and ocassionaly get a pop from the exhaust now and again so that means its still a tad rich which is good at least i kno my car is not leanin out , fuel economy has increased from 250 300km city driving to 350 +km. Im just not sure if everything suppose to be in the negative like that as i have noway of checking my air fuel ratios cus i have no wide band sensor or even my hp cause dynos are hard to come by, but I can feel the diff in acceleration and see it in fuel economy. I just wanted to know from those who have piggybacks if there settings are all in the negative like that?

everything is fine mate.

The standard comptuers run too rich standard and when tuned in most cases there is fuel taken out across the whole board.

correct.

I have tuned a SAFC and most of the tuning is done by simply taking out fuel.

Most of the fuel takem out was 30% - which was alot. The car still ran richish afr's too.

I didn't want to take anymore out just to be safe, as I had the impression that the fuel pump was wearing out.

      Just to be clear, there were no lights or codes when the hiccups were occurring. Also nothing noticeable in the cars' braking. It brakes fine and the dash is clear. I only made the connection when it did throw a code and suddenly, despite the lights, it felt great again.

      Yeah they are sliders and this was in my head before I worked out it was the speed sensor.

      Ok so we have a smoking gun.  A few weeks ago I had to replace a speed sensor that I'd fit incorrectly. I replaced the sensor and everything was fine with no lights or codes thrown any longer.  When I was doing some more bedding in yesterday I got ABS and traction control lights again and, considering when this happens those things are disabled, the pedal went back to normal with smooth braking and no hiccups.  The codes thrown are for the same speed sensor that I replaced. When I looked at the sensor I took out it looks like the tip of the sensor is damaged. So whatever happened to it, perhaps it has damaged the magnetic ring on the bearing (that I only replaced the other week). I'll get my boroscope in the hole where the sensor goes and see if there is any damage in there. Hopefully just the tip of the sensor is in there and the bearing is fine. 🤞🏻  It's worth noting also that the pedal hiccup happens more often and for longer periods now and totally goes away when the codes are thrown again which happens usually after 5 or so minutes of driving. Love all your help here as usual guys, thanks!
