sstt tuning box for sale


Recommended Posts

SStt for 135i/ 335i tuning box for sale, removed this from my 335i recently had a full remap. The tuning box is approximately as new. We had the car on a rolling road and the results are as they are advertising, I have a graph available for proof. Pound for pound i don't think there is nothing better or available. The results show 30hp using 95Ron should improve if you use higher fuel grade. Can be removed in minutes before service and warranty claims. Costs $600 to buy new from the states, for sale for £200. Please contact me if you are interested. Please read Split Second for more info.
