twin throttlebody VT 304
Hello can you give me a tune for my VT 304, pace makers freeflow 3'' no cats , std cam , but twin throttle bodys. Twin pipes and airflow meters,I am only using one meter and the tps on one throttle body. Was thinking of fudging it with bigger injectors to compensate for the extra air.???Has anybody got a easy way ? was thinking of getting a memcal from chiptalk.

Twin TBs is going to neccessitate a fair bit of change. I dont think your going to get it running well without doing it properly.

Maybe so (and Im not saying you should be ripped off) but if you dodge it up you'll miss out on a lot of performance, and might find your better off going back to stock with a good tune. This way you'll have the right enrichments etc for the expected inrush of air when the stock TB opens and the right dead time settings for the stock injectors for accurate fuel delivery. Of course you can and maybe should do it yourself. Have a skim over the FAQ (link up the top right) to see some documentation and Q&A.

With the changes you've done may be worth considering going to 11P.assuming it's an auto. Will be easier with MAP with twin throttle bodies and supports the electronic auto and VT dash I think.
As it's not something many have done trying to get an off the shelf tune will most likely cause problems, better off doing a custom tune to suit.
If it's a manual could use 12p as its MAP based and also now supports VT clusters.

Ok I have at this point in time got on the LS1 airflow meter,the 70mm throttle body and the 220i tune, its runnig well, the easiest is I think the ls1 air flow meter on to the twin throttle bodys and blue top injectors if its going to lean. I dont think it will lean out as the inlet mfld has std diameter runners with length tuned to bellmouth.The flow is i am told 500cfm on std runners so the twins wont give any more top end air. The exhaust is pacemalers into full lenght freeflow twin exhaust and resos. This should be able to get a off shelf tune? Its a getrag man, I love the easy shifting as opposed to my T56 maloo.
