Alright guys, the wait is over. The 350 tune is now ready! The first revision is for sale starting May 3, 2010. Any future revisions will be free. This is a $100 upgrade for those that already have the 310 tune. Remember that this is an all out race tune. We highly recommend that you use this tune in conjunction with an aftermarket transmission. Head studs would also be advisable for those that plan on running this tune. Remember, this is an all out race tune that is more than doubling the stock horsepower output. Play safe!
