Just want to thank Goshan and Jags for all the hard work put into my car. ECU Tuning Group has flashed my car along with their pulley and all I can say is wow! It is night and day. The car is so much more powerful now with a lot of torque. Car has Mina Gallery exhaust, pipe, and K&N filters plus the tune and the pulley. I am still waiting on my Twin Cities Performance Intake to come in so I can see what the car makes at Borelli Motorsports's Dynojet. Car has fully adapted and gets faster the more I drive it. If you are on the fence about doing the tune and pulley, go for it! You will not be disappointed! The acceleration even in 6th gear is night and day. What else can I say, I'm pretty much speechless. Of all the cars I've owned, this tune did the most for the car. Would like to see more X351s that are modded. It seems like the XFR tuning world is huge.

 

Just put down 491WHP 453WTQ on a Dynojet at Borelli Motorsports today in San Jose. Power would rise after each pull. Total of four runs. Can't be anymore happier to see these results on my car. My intake should be coming in soon so I don't see why 500WHP would be a problem.

Great results, makes me want to swap for an XFR more and more when I see threads like these! I'm sure you'll see 500whp+ with the intake or boring your TB which are both cheap mods.

 

Just wondering if you still have the car. Have you seen any issues since? Have MPG's increased or decreased? I'm thinking of doing this to mine.
Thanks for your time.

Sup fellas,

I still have the car but I have a different tune now. ECU Tuning Group told me they were unable to reflash my car after I got the Velocity AP 200 Cell Cats. So Chris over at Velocity AP sent me the OBDII Tune box to tune my car to accept the cats. I shelled out a lot of a good $ for the ETG tune but was surprised they did not offer retunes for added modifications.
My car now has 48k miles and runs strong to this day. Gas mileage if I’m cruising is 18-21 MPG. I also added the Mina Gallery intake which is way better than the TCP intake. More metal, less rubber couplings for the intake.
I drive the car very spirited most of the time and the car has had no issues. I recently had the fuel pumps replaced under warranty because the car was hesitating to rev over 4K and felt like it was loosing power. After getting the car back from the dealership, the car has given me no issues and I pretty much leave many people surprised on the road because of how quick the X351 XJL SC is with full bolt ons. I like the fact that not many people know how good the AJ133 engine is in terms of performance. Reliability wise, we will have to wait and see! I’m still on my stock water pump and haven’t had any issues with it thus far.

Very nice. I had an XFR tuned by Jerry over at Eurocharged and with just the tune and pulley it was a monster and went 11.89@118mph on street tires (which I think is a record for Tune and pulley only XFR). I was recently rear ended and the car was written off and just bought an XJ Supercharged as a replacement and have started the modding already.

Have you taken your your car to a drag strip to see what it will run?

That's an amazing time for a 2.6 60'. You get that to a 1.8 and you will be in the mid 11s for sure. I miss the more sporty feel and look of my XFR but so far I'm liking the XJ-SC.

 

Johncy, what was your trap speed?
