I got one. Installed it about 2 weeks ago. It does what it says it does. Factory smooth. More power. No CEL.

I havent run anything scientific mind you but before, when you stomped on it you could see a cloud behind you. You still can, just not as bad. I swear my MPG went up slightly.

Take it for what its worth, but it was $220 bucks well spent.

That speech is worthless without posting 0-60 times before and after.
Same when it comes to mpg
If you had smog before, your engine had something bad happening.
Doubt chip can fix it.

You will usually find the mpg readings on the dash will be knocked out as the box lies to the ecu to deliver more fuel and boost.

Never been a fan of tuning boxes, if the warranty has run out then I'd never bother fitting one and just go for a generic stage 1 map instead, just my opinion obviously.

I havent gone as far as that but I suppose I should.

Factory tunes are typically quite rich. Aftermarket tunes usually lean out WOT fueling and could cause a reduction in black smoke.

For diesels?

I took off mine after 1.5 years of use.
it was giving too much pressure & the fuel pressure rail sensor reads it & it disables the engine. It has stopped my car on 2 occassions while driving on a busy expressway.
