I drove it over the weekend for the first time in maybe 6 years and was so impressed
So I plan to get the fender rust removed and have it repainted and plan to keep it in the family.
When I do the body I'd like to experiment with engine upgrades
Is there any plug in chip upgrades for this engine that can boost HP a bit?
Nothing crazy, maybe another 30 hp or so.
Also I hear of injection pump tweaks that add power. The Brits do a lot with of this stuff.
Any advice is appreciated
thanks

Chip?

chips are obd1 kinda things, im pretty sure even benz's 96 newer are flash based operating systems.

Edit~ looks like they stayed old timey post 96 til.........................

Where'd you hear that? Most european cars used EEPROM chips well after OBD2. The flash based chips that are field programmable weren't until the late 2000's for most european cars. My wife's 2008 Volkswagen still uses EEPROM chips. VW didn't switch to flash until 2009.

By US Federal Law at least, EVERYTHING '96-newer (OBD2) is required to be flash programmable. Of course not everybody listened. We flash program all of the BMW stuff, and have various bench flashing rigs setup to do it on the bench, no need to have the car. I was shocked too when Jeff said chips had to be removed & replaced. I think it's more likely that most people don't have a flashing tool & checksumms for these ECU's than it can't be done.
