Not sure where you're located, but it's all about the fuel. What kind of fuel do you have access to?

Im from Bahrain pump gas 91 octane.

Assuming it's 91 PON (US ratings system) without ethanol blended into it, you shouldn't have too many issues with tuners. We can tune the car through the OBD and email using the MyGenius. The only issue would be the TCU tune, as we'd need to have the TCU here. The same is true, I'm sure, for just every other tuner.

just get a ec box tune with sc pulley and you are good. good price too. they can ship to your door.

didn't realise that the 55k needed a TCU tune, many have run for a decade with out it

"Need" is a strong word, but you can definitely improve your 1/4 mile MPH and ET with a TCU tune. We've done quote a lot of them over the years, with many happy customers.

So do yall tune E55's? You dont have them on your website.

Speedriven1

We have tuned and built E55s in the past, but yeah- we did recently remove them from the website since there didn't seem to be much interest for a while. It seems like they all have the ECU and pulley, Kleemann is blowing out headers so cheap it's not worth making 'em, etc. Now guys are starting to really push the envelope with built transmissions and sleeved engines with billet pistons and things like that- so we'll see. They may need to make a comeback on the site.
