J+M is very well disliked in the LS world. Mostly due to the overcharging and lack of tuning knowledge. I'll bet the car is not full VE tuned,that you requested, and they have the balls to give you uncorrected #'s which mean nothing except they could very well be 20+hp more than the corrected #'s and of course make them look great.Add that to the TSP STD #'s and the car just hasn't been measured correctly yet. Well, except when it dyno'd here with corrected #'s that are now comparable.
I would have charged you $250 for the pump too.The shops have to make a profit but I would of diagnosed the real problem first since these cars don't run out of fuel pump at 430rwhp or so.
Either way the car is done and hopefully running right. Now you can enjoy it.
