16 Turbo lag

[Elementality158]

If you have a boost gauge in the car just have someone watch the gauge while you fill. Fill it to 20 or so. Then watch it drop. If it goes fast, then bad. But if it stays up there real well. Then you have it tight Listen for any leaks, they can be in the weirdest spots.

I can relate with a bad boost leak.

1) Check the turbo bolts and gasket (the bolts fastening the turbo to the exhaust manifold). I once had those bolts back out and it was extremely hard to build up boost.
2) Check the upper/lower intercooler pipes (especially at the couplers). I once had the clamp on the lower IC pipe loose and it made it difficult to reach full boost.

It sounds like the problem is your Vet makes 517whp and 490trq and your DSM would be lucky to make just over 1/2 that. I would do a boost leak test, check all clamps, pcv valve, exhaust manifold bolts, boost controller settings, turbo shaft play. Fuel mods should be somthing like Walbro 255, ajustable FPR, 650cc or similar injectors, SAFC 2, and a FMIC would help.

lol, the Vette sets the bar pretty high. It's tough moving between the cars that's for sure. I have an unexpected issue with the Vette at the moment so as soon as I'm done with that I will be revisiting this and will be sure to post the results.
