No, never regretted the switch. I did my first one in 1995 with a thermoquad to projection, it is still running 117,000 miles later, with 3 throttle position sensors, one my fault washing the engine, the others pretty sure the forward and backing of snowplowing is the main cause, the sensors wear and it gets erratic pedal response, but does not quit, one fuel pump failed right away, black holley pumps were junk, switched to the bigger walbro pump. It runs in -20 pushing snow into 6 ft piles dead cold or pulling a trailer at +100. A lot of people failed with these systems, all I did was all new feed and return lines, pump mounted lower than the tank, away from the exhaust to keep it cool, a good filter before and after the pump, and an alternator that provides 100 amps at idle 14 volts and never drops and starves the system for voltage. It was the best thing I ever did to the truck and every 5000 miles the oil is still clean, so pretty sure the engine will never wear out, I might blow it up but the coloration of the oil was a surprise. Maybe I was lucky but I really believe the charging system and full voltage always is the big deal. 14 mpg at 6700pounds, extended cab 4x4, 35" tires, towing a trailer with a 3600 pound e-body with the air on. The thermoquad could only dream of this, just a 318 with 1992 magnum big exhaust, slightly ported heads, performer intake, polished chambers, bronze guides, stock rerung shortblock, and a new 360 2bbl cam, all junk I had laying in the shop. I figured it would last 5 years, so it owes me nothing. I did have to replace all the steel fuel lines again as the salt brine ate them up. The other good thing is I bought several so called failed setups at swap meets for 50 bucks, so I have plenty of spare parts. I have even run it completely out of fuel, because the gas gauge quit 15 years ago, no problems to the pump. Almost forgot the relays supplied in these kits suck, I switched to mopar factory 30 amp relays and pigtails and never had a failure after that.
