I think that Woodhouse is unique among dealers with respect to its modification capabilities due to the fact that Woodhouse was/is an active racing competitor. Their performance capabilities were, to some extent, developed and honed from prepping Woodhouse car(s) for racing. In addition, they have been modifying Vipers for the street for quite a few years. Mark's ability to pick up the telephone and speak to the SRT engineers is an important data source. However, once again, if one wants to alter the stock Paxton supercharging kit, an independent tuner is needed. Those who do not care about the Paxton three year limited warranty or the optional Paxton driveline warranty, assume the risk of any resulting damage, if any, from the alteration of the kit. Some also, based on quite a few posts on these forums over the years, do not mind if the overall engineering integrity of the car is not maintained. ( Paxton thoroughly tested its kit and with feedback from people like Dan, Doug and Mark have refined the kit .) In other words, a dramatic increase in power is produced without strengthening other related components. I think that the proper way to mod is to look at the car as an organic engineering whole, as SRT does, and act accordingly. This requires good data - not just hearsay and anecdotal first hand reports by Viper owners. This is one of the reasons why when I read a post about some new mod I ask for data about its efficacy, durability and reliability. If the data is not provided, it's a good bet that the component has either not been tested or not adequately tested. For me, no data means no purchase. Others may be willing to experiment with their Vipers based on blind faith. That is fine as long as they understand the risks inherent in doing so.
