Have you received your MonsterX tune yet and if so, have you installed it. Eagerly waiting for update on how you like it and more importantly how your car likes it.I just bought the 87-93 tune, I already have an ap. The tune is 300. For the 93 and e30 bundle its 400. I used promo code (monster10) it gives 10% off. So I paid 270 for the tune.
