Keith’s Blog: Is It Chip Time for Sluggo?

Keith Martin Avatar

It’s not “doomscrolling” for a car guy, it’s cars for sale searching. Those of us who are addicted to finding “just one more car” can’t help ourselves. In addition to the usual suspects like Bring a Trailer or Cars & Bids, we look for slightly more obscure sites where “the buy of a lifetime” might be hiding. I’ve recently discovered Facebook user groups as a source of fellow fanatics, in my case Alfa Romeo S4 Spiders and U.S.-spec Lotus Elise S2 models. In addition to doing deep dives, on topics such as whether or not the shifter position indicator on an […]

    Keith,

    Would you actually be even able to feel/perceive/notice a 10hp increase? I say save your money!

    Sadly, I don’t have an Alfa currently to compare, but as to chips for improvement, I can tell you that we “chipped” our VW Tiguan with a product from APR, and the lowest state of tune (Stage 1, 87 octane; it is a tin can daily driver after all) made a huge difference in driveability across the range and even picked up about 2mpg overall in ‘normal’ driving. Highly recommended. With an automatic, you might like to search for an item with a bit more initial gain, say 30 hp or so, but expect a tangible improvement with any of them.

    Keith – not an Alfa Romeo or a Lotus, but I have chipped (and still own) a 2018 VW Golf R and at the same time increased the turbo boost pressure slightly – it went from a factory 292 hp to approximately 350 hp – very reliable, never had a problem – and surprises many BMWs.

    I doubt that you’ll get too many responses from folks whose chip switches didn’t go well.

    I’d trust the engineers and tech at Alfa Romeo for having already figured out the best “all-around” chip for the car. There are plenty of way to get a few more horsepower out of an engine, but Alfa decided on the set-up it came with from the factory. You’ve probably already helped boosted the power a bit with the exhaust. But that alleged 10 extra horsepower from the chip just might take 20,000 miles off of the engine’s life.

    If you want a quicker car, there are plenty of them out there, so sell the Alfa and buy something quicker.

    my automatic sluggo turned out to be a screwed-up cam timing actuator. transformed the car when an experienced tech fixed it!

    Having owned two S4’s – one red , one yellow,
    They are Led Sleds….I also looked into chipping both of them but the cost benefit of just gaining 11-12 Hp at the sacrifice of cam wear just isn’t there ; in your particular case of an S4 being an Automatic , I say absolutely save your money . Keeping your S4 original will make it more valuable when you or your son goes to sell it ! “Chipping” a car is akin to “Tracking” it !…. This devalues the S4 greatly as it would most any other car !

    Do it! My S3 Spider has always felt less eager than I think any 2-litre sports car should. I looked into various ways to pep it up a bit, but eventually swapped the engine for a tuned S2 with SPICA when one became available locally at a good price. Probably more work (and cost) than you want to get into, but it’s a major transformation in responsiveness!

    Take it from a mechanic…NO!!

    I fix engines all month long that were “chipped” – then ruined.

    You should see what a “performance tune” can (and will) do to a diesel engine.

    DON’T DO IT!!
