Built/Tuned by Boost Performance in Amarillo TX.
Bone Stock Motor
2.3L Whipple @ 23lbs

If you have specific questions about my setup, feel free to ask.
Ok, now onto the testing and results. I have been running the stock intake tube, C&L MAF housing, stock sensor, MAFia and a big K&N filter. The reason I never installed anything different is because I didn't like the looks of any kits on the market. I didn't want a metal tube that would get heat soaked, and none of the plastic kits looked good IMO. I talked with Jared at Lethal a few months ago and he told me JLT had a new kit they were about to release. This was exactly what I had been waiting for. So I forked up the coin for the new kit and I must say that it was well worth it.
To start with we wanted to get a baseline number. We strapped the car down and made a pull to the tune of 658/680. I was standing next to the car watching just the boost gauge. The gauge spiked to 23lbs, the slowly started to fade to 20lbs at around 5300-5500rpms.
Ok, now that we have the baseline it was time to start the install of the JLT High Boost Kit with SCT's BA3000. The install took no time at all. It was pretty straight forward as a CAI install should be.
We spent a good bit of time making sure we had a good A/F ratio before we made a full pull. We finally got it close to what we were at before and made the first pull with the JLT kit installed. 677/735!!! I could not believe the massive torque gains!!! It made 60+ more torque at 3k rpms!!
Once again, I watched the boost gauge. I was hoping that the added airflow might have helped with my boost drop issue. I wasn't so lucky. My belt is still slipping. Spiked to 23lbs and dropped to 20lbs again.
Now we decided to see if we could get this fixed. We went to the store and bought a shorter belt, swapped it out along with a idler pulley off a GT500 to fit with the tighter belt. I released the tensioner and the belt was SUPER tight now!!! We made a small adjustment to the tune too. Added just a little more fuel up top. The next pull netted us 681/724!! A/F was great, but the belt was still slipping. Did the exact same thing it had on the previous two pulls. 23lbs down to 20lbs by 5300rpms.
We gained 23hp and 44tq at the tires!!! I can't express how impressed I am with this new kit. We also looked at the downstream air temps from before and after. Run 1 was 125, run 2 with the new kit installed was 98!!! Amazing!!!
I'm sure there are some other details that I left out, but if you have any questions about the results, please feel free to ask away!!! If anyone is having second thoughts about buying one of the new JLT kits, DON'T!!! Do yourself a favor and let your car have some air!!!
I also want to give a Big thanks to Boost Performance in Amarillo TX for all the help with my car over the years!!!
