[QUOTE="fbody83, post: 15856352, member: 8218"] A friend of mine is working on picking up a twin turbo 03 cobra that's currently tuned on 60lb injectors and 93 octane. He's going to put bigger injectors and run e85 in a few weeks. I've successfully tuned my 03 cobra via PRP which has a 2.9 whipple, custom cams ID1000's and E85. I'd like to give his a shot and I would think that the tuning between the two cars won't be too different except for MAF and spark. My main question is related to the spark table - On an 03 cobra with a PD blower, boost is instantaneous so at WOT in the lower RPM ranges, it's a good practice to keep timing low and ramp it up as RPM's increase. In a turbo car, is it common to do the opposite to help the turbo spool faster? For example, get more aggressive with timing in the lower RPM's as the turbo is trying to spool and then bring spark down a little bit once it hits boost? Any other best practices or tips for tuning a turbo cobra? Thanks in advance. [/QUOTE]
