When I first opened the box I knew I was dealing with a professional. Everything was labeled, all wires were placed in high temp flexible loom, all wires soldered and heat shrank etc. You get the idea PROFESSIONAL! Install was very simple and straightforward, took me eight hours with breaks for food and drinks. First time start up went well, but I had some pre-existing faults with my ignition system that were magnified when I installed the TBI system. It took us a while to figure out what it was but it was nothing to do with the system. Periodic miss at #1 cylinder, couldn't get timing light to fire all the time, faulty brand new plug I installed. Replace plug, no problem. Two burnt spark plug wires and problem with mount on TFI upgrade.
TBI performance etc. If you don't have one on your Jeep now you will want to save up for a system. My Jeep has a somewhat radical cam listed at .488 lift intake and exhaust at 218. I was getting 11 mpg on the highway and somewhere between 5-8 mpg in the city. On the highway I consitently get 15 mpg, don't have to worry about ping at all, I run 87 octane cheap gas instead of 93 octane. I have found the Jeep has a much broader power band than before and sshe has nor problem blasting from 60 mph to 80-90 mph with ease. I know they are not race trucks but trust me it was nice to see the improvement. City driving mileage has increased to a steady 11 mpg and there are no stumbles or hesitations associated with carbs.
Off-Roading Review- Well I had some time to take her out and boy it was amazing. On inclines I did not have to worry about the carb loading up or stalling, she just sits and idles. I was so impressed I sat and idled for a few minutes almost vertical in the name of science. We did some deep water crossings over the rocker panels and to the middle of the door and no problems. Throttle response is excellent, no worries about stalling or flooding, truly awesome. Mileage was incredible as well. I burned about half as much fuel as I normal would have in the same trip.
Customer Service- One thing I can say is John Wilson (TPIGuy) stands behind his product 110% I cannot say enough good about how much help he has provided me and the knowledge he has of this system. I have used my laptop to provide him with info on how the Jeep is running, he interprets the info and burns a chip based on this. I wait a week and I reinstall the new chip and am always surprised to see how much better it runs. I am always sure that this is as good as it can run and John will tweak a value here and there and it is a noticeable difference. For those who can not wait for the chip to be mailed to you, you can choose the option I did. I borrowed(deposit down)on an EPROM programmer and eraser from John. He now e-mails me changes and I burn the chips at home and don't have to wait for the pony express. My cam is one of the more radical ones John has dealt with and it has taken a little longer to fine tune, but we are 99% there. As far as stock cams are concerned John has a chip that is fine tuned for a stock 360 and will work well with minor adjustment due to engine mileage or abuse. When done with my truck, he will have an awesome chip for higher lift cams similar to mine.
If you can't tell already, I am totally happy, satisfied and feel TPIGuys product and service are second to none. If you think Holley or anyone else will work with you like he did, YOU ARE OUT OF YOUR MIND!!!!
Please respond I would love to hear from you guys.
