I installed SDS way back in 2004, still running the same system in my bug but I re-chipped it to the latest version before V5.
Likely I'm one of the first here running a programmable FI system, at least on a DD. http://www.sdsefi.com/ My 914 I ran it on a stock 1.8 and 2.0 with a mild carb cam with a pretty well stock D-jet intake (intake used on both the 1.8 and 2.0). Both engines ran flawless, perfect AFR, on the 2.0 I took the programmer off and ran it for 3 years (6+ month seasons) without ever checking it. I'd say it ran like a brand new L-jet, turn the key and go. My bug is a super hi-performance 2.6L T4, 102x78mm, nickies, JE's, 2.0 big valve heads, Web cam, A1 1-3/4 exhaust etc, etc... Only issue is because of the 46mm ITB's I can't get a good MAP signal and I have to run it as a TPS only system which may hurt my MPG slightly. But then again it still runs flawless even on TPS. I can tell you for 100% sure PEFI doesn't add a single HP, but it can run things, like a performance cam, that stock FI can never run. |

PEFI alone adds no HP, but a proper tune on top of that PEFI will, especially if your system is controlling your timing as well. Having a full 3 dimensional tuning table for both fuel and spark allows you to dial in the tune and give the engine exactly what it needs everywhere.
