I real nice man from Jacksonville has a black Trilogy, and brought the car by, it was having severe issues at wot he thought it was the transmission, after driving the car I was convinced it was not the transmission, he has had the car for three years, and it had 48K on the clock, it has never had the IAT mod or the FRP sensor, so I told him I would put it on the dyno with his stock tune, and we would take a look at it, it had a chip in it, and after one pull the AF needed adjusted, and the car made 368 RWHP. So I opted to re,do the tune and make the fuel rail pressure sensor boost sensitive. I also pulled out the 22C plugs and installed NGK TR6. Below is how we cut the boost line and splice a T fitting in and run this around to the FRPS so it will see boost at WOT and we just cap off the OEM line that only sees vacuum.

Now my dyno can read boost, so we just T off the FRPS and I can see how much boost the car is making at WOT on the dyno Graph.

Now in a few weeks he is going to bring the car back and we are going to pull the intake, and install a IAT

And at the same time I am going to install the same reservoir I use on my Vortech kits, because it will hold more coolant.

Now he made good power but we backed it off till we can install the IAT, the AF did have a slight, lean spot but we corrected that on the next pull, we got the car down dialed in the shift points and he was very happy.

And you can see the car made just over 9 PSI
