Have a few questions for anyone who has this kit on their 94/95 Cobra or GT.

What questions do you have? We might be able to answer them without helping...there are a few S trim users on the board.

Looking for install tips/hints for this kit using the Powerpipe, Mallory HyFire w/3bar MAP sensor. Where did you mount the unit? Any concerns issues? I was told to set base timing @10 and set Mallory for 1 degree retard/lb boost. Set base fuel press to 40 (vac off) and use the T-Rex and 4:1 FMU. I'm installing Lucas 38# inj and have a Walbro GSS340 in tank. AFM still recommended installing the T-rex and the FMU.

Folks have said its harder to tune w/the FMU installed.

Looking for ideas/suggestions from those that have this kit tuned.

You will need to keep using the FMU with 38lb inj. When you go to 42lb inj and up you can get rid of the FMU. But then you need a way to drive the inj harder if more fuel is needed at full boost. The FMU can get a little fussy at times. You will usually get a sudden jump in fuel pressure once boost comes in. As far as the T-Rex goes I would listen to Rick at AFM and put it in. You can watch a fuel pressure gauge with and without it. If you start losing fuel at mid track you will need the assistance of an additional fuel pump. I think in your body style you can mount the ign box on the bulkhead(firewall). Otherwise inside the car under the drivers seat works to just make sure you have clean and tight connections when doing so. Also I noticed you are using a kirban fuel pressure reg. The unit will go 1:1 under boost. Meaning for every lb of boost it should raise fuel pressure by 1lb.

Thanks,
Your recommendations were exactly what I was thinking. I knew the Kirban would do 1:1 under boost. I had been told by others that you could mount the ign module under the driver seat too. Seems like a long run for the wires though. I'm going to do my best to locate it along the firewall.
