[QUOTE="moncho, post: 15881482, member: 128236"] I have recently installed a Whipple 2.9 Gen3 on my '07 GT500 and have a similar issue with hesitation just not as pronounced. This issue appears to be crossing platforms so it's not a GT350 or GT500 only problem. I reached out to another reputable tuner and he confirmed my tune was spot on, however he had concern about the plugs I was using. The plugs are the NGK Tr7IX, gapped at .028". He stated they are very cold plugs and could cause spark blow out. He recommended the NGK TR6's, so I swapped them out yesterday but haven't test drove the car yet, not getting my hopes to high. I'll upload my hesitation datalog along with a 3rd gear pull. Don't have access to "LiveLink" to help determine at what point the bypass actuator closes but I think it's close to 0" Hg. If someone can verify with the uploaded datalog file that would be great. I'm currently running @ -16" of Hg at idle & up to 17/18 psi of boost. Car is a beast that's for sure. I have reached out to Whipple and have gotten their support, however for some reason their tech support is extremely busy. Could it be because of this issue? I really don't know. The following is a video I took using my scope to help determine the bypass actuator operation: Here's a [URL='https://onedrive.live.com/?cid=1CCCE97CAEB32A14&id=1CCCE97CAEB32A14%214841&parId=1CCCE97CAEB32A14%214836&o=OneUp']link[/URL]... Whipple confirmed it operated as designed. [I][B]EDIT: log022_Hesitation_R2 was a revised tune. log025_Hesitation_R3 was also a revised tune but adjustments were made for the hesitation, which moved it up to about 1800 RPM instead of idle RPM.[/B][/I] Toni - thank you for posting this thread & I hope you don't mine me uploading a few files.
