Default 75mm throttle body

I installed a custom built intake with a 75mm ford tb. The tb has a 3 wire ford tps and a 2 wire ford iac. after wireup everything works like its suppose to, however, when i'm looking at the tps sweep on scantool its going from 0.8v closed throttle to 4.5v wot. I know that 0.8v closed is normal but 4.5v wot??
old tps only went as far as 3.8v

So you ARE still using the Ford TPS and IAC? Or no?

Why use a ford TB when there are plenty of aftermarket TB's made for our car?

It shouldn't make much difference as far as function goes. Sure is a big throttle body for a mild sized turbo.

If it still has a smooth transitions between open and closed loop fueling and the car performs how it should, I don't see a problem with it.

The factory PCM only requires 2.3 volts from the TPS to enable WOT power enrichment, so as long as you are over that then you shouldn't have problems at WOT.


Send me a log

Throttle response in unreal, I see a big difference in how the car is performing.

Also With the new tital WG I installed, I'm still playing with the MBC trying to find a happy medium 3rd gear 4500 rpm spiking 22psi afr 11.2 and clutch is starting to slip lol what's next. I'll send you a log in a couple of days.. You think we might have to do any re-scailing with this intake? Stage 2+ clutch on order

All depends on how the log looks.

Also, if you haven't already paid for the clutch, you might look into something a little tougher than a stg. 2
