Wish i could get mine re-tuned by wheatley

 

Whats the dealo? do tuners tweek the VVT??? is it only done hands on??? the tuners what are they getting more with a final vvt tweek on a good tune??

 

not sure but i dont think the vvt is messed with in a tune if it is stock and you are just tunning it.. Just TM, shift points etc... I believe only vvt messed with with one of the folwing is done.
1. deleted via tuning if a NON vvt aftermarket cam is installed, which requires an ls2 cam gear, timing cover and a reg ls based style cam.. (ex. 3 bolt cam).. and something that i might no remember right now
2. or if u install a vvt cam along with the installation of cam phaser kit to limit degrees of timing, comp and mast both have a few of those.. and those do require some vvt tweeken...
wheatly or others can chime in and better explain.. still trying to figure it out myself lol

 

VVT tuning turns in superb results but for each change in cam timing it also messes with ign timing and fuel trims so it adds a whole new dimension of complexity to tuning. Heres a quote from Patrick G over at Ls1tech

 

Thats what im talkn about! Has to be something about maxn cam timming,I want to believe in maxing the VVT before a delete with a aftermarket cam

 

Yeah VVT tuning is still pretty new to the GM scene but as it unfolds VVT is a HUGE part of the future for GM and the aftermarket. Theres really no arguing against its benefits really it gives you more power under the curve than a static cam ever could. The only real issue we have right now is PTV clearance as this is the limiting factor.

Im build a 6.2L t56 87 Camaro swap retaining VVT now. 222/230 .600 cam LT's etc etc. Should cook along quite nicely once its all said and done. Especially considering I'll be at 3300lbs ( already had an LS1 in there and weighed it so thats how I know 3321 or sumthin )
