Hey mate,
congrats first on getting the car back and working out the issue of the boost drop
do you think this would still happen on the .86 models of the same turbo's with IWG? Reason I ask is if I eventually get my GTM kit, these are the turbo's I will have and eventually up the boost over 10-11psi once I upgrade to an e85 compatible system.
I also missed which GFB product you have, is it the newer style G-force II? I've got the same one but haven't really seen any reviews of it yet.
