If I had it to do over again, I would go with a Zex "wet" kit. The box has been altered alot since I bought my dry kit. The box is half the size it was.... and being able to mix the fuel in at the same time is all the beter.
If you don't plan to pay the price for a bottle heater, the zex kit is one of the few that adjusts according to bottle pressure. I've seen this work first hand when racing in the middle of winter against a similar calibur mustang with a different kit. The other kit dropped the hp a lot more with a cold bottle as the shot dropped his fuel pressure remained the same, basically giving him a bad tune (too rich).
