Ok so let’s talk about e30 tune from monster tuned! I’ve been tuned by stratified and by all means I loved their tune. When I got the e30 tune from monster my car literally felt different. Ran smooth as can be with no issues at all. Literally felt like it was straight from factory again with a huge punch of power and top end. I get very minimum knock or ignition correction. Also if you have any questions about your car or the tune and you ask the tuner you hear back within a day. Out of a 5 star rating this definitely gets a 5. Once I order the new tune I will definitely be back to let everyone know how that tune compares and if it makes any difference! Great job monster tuned. Keep up the great work!
