Well, the installs went smooth and all is done/running well for weeks.

The DSX Flex Fuel is a breeze. Simple and straight forward. It’s more confusing and intimidating reading the instructions, than doing the work. Basically, you unplug the fuel line and plug the sensor in between . Then run the wire from the newly installed sensor to the designated pin on the ECM. Another wire runs from the flex sensor to an ignition coil. It’s easily done. If I had to do another one I could probably accomplish it in under 15 minutes.

The DSX auxiliary fuel pump is a well thought out, well engineered kit. It’s nice to see aftermarket engineering that is made to OE standards. Right down to the length of the hoses and the wires, everything is well done and planned out. My compliments to DSX.

On a side note, if drilling a hole in your fuel tank is not your thing, get some help with this part of the install. Use an air drill and ditch the old school drop lights when working with fuel. Run your car down to near empty and lift the rear to pitch the fuel away from where you are drilling.

The idler relocation bracket was an easy install, as was the thermostat. I took advantage of the extra room while I was doing the relocation bracket and tossed the thermostat in at the same time.

As far as the injectors go, that wasn’t my favorite part of the mods. It was about 90 minutes of angling and working pitches to get everything removed and seated. The front bolt that everyone shaves down can be done without the trim. An open ended wrench standing straight up will work on that poorly placed bolt. I would skip the grinding and depositing metal shavings everywhere. I didn’t enjoy this part of the mods, but wouldn’t hesitate to do it again.


Someone on here said the header install was one of the easiest he had ever done. I would have to agree. My 79 Camaro small block was a bear in comparison. No mods to do with the Dynatech headers on the ZL1, everything unbolted and bolted up easily. Plenty of clearance and room to work. No regrets and it sounds awesome. The High Flow cats bolted up exactly and fit like a charm. No leaks, no issues and no problems.

I haven’t run E85 through the tank yet. Winter is here in the North East and I don’t want to store it with E85 in the tank. I can’t wait until spring when I can introduce E85 into the equation. The headers, high flow cats, DSX auxiliary pump and injectors are supporting mods. The only power difference I am really experiencing is the increase in lower pulley size (10% OD versus the new 18% OD). I can definitely feel that difference . Even with the Toyo R888R’s , punching the throttle at 35-40mph will break the tires loose. The car woke up and has a new personality.

I bought everything from JRE and Ted Jannetty did the tune. It’s flawless. The power is absolutely instant. The car drives like its 100% stock. No check engine light, no reliability issues, no stalling, smooth idle and no issues at all. Thanks Ted and crew. I wouldn’t hesitate to buy anything from JRE.

All in all, I would do everything again and recommend it all to anyone looking for some solid increases.
