Another vote for VMP. I did their "730hp" upgrade pkg ( 82mm pulley+ BAP) last fall with ngauge and added the JLT intake. Wow! night and day difference over the Roush 670 tune. Could not be happier with it.
Ngauge is very easy to use. I like the fact that I can actually use it as a gauge. I have it mounted in one of the vents. Their intial tune was spot on. I watch some parameters for my own curiosity but data logging was not a requirement from them like some others.
VMP now uses HP tuners with the nGauge so no longer the need for the harness. The stock Roush tune can also be reflashed back to stock if needed.
I got the VMP 730hp upgrade tune + JLT CAI during their back to school sale. The difference between the Roush 670 tune and the 730 is night and day...
I could not imagine traction with those tires?! I have 315/35 mpss on my Roush stage one and I can light the tires up at will in second gear and quite often in 3rd! 3.73 gears though.......
I have the same issue. Surges every so often under steady cruise. Other than that seem to run "ok". Have a VMP tune on order should be in next week. Hoping it cleans up the part throttle a bit. I like the fact VMP now use the nGauge and HP tuners so there is no need to swap out the Roush IAT and...
Stinger is a phenomenal vehicle....and by far the best all around bang for the buck perf sedan in the Canadian market( Our pricing is much better than the US and we get some other options the US does not). I will be pulling the trigger on Stinger the very near future for my daily. Still keeping...
Kit came in today. Pulled my stock file to send back to them. Now I wait.
I also received one heat range colder plugs. What are you guys gapping your plugs to?
Pulled the trigger today on VMP's 730hp upgrade +JLT CAI. They have a 15% off sale till the end of the week so that was my incentive. Will start with the 730 kit till i do OPG's. Will update with first impressions once I receive..
Can you define "a little while"? lol Did this take multiple back and forth with them? SCT or nGuage? I thought that nGauge is supposed to simplify things now concerning the Roush tune...
Nice mph! Did you ever get this on the Dyno? Was VMP's tune spot on, first try..or did you have to do some back and forth with datalogs? Im still on the fence on what to do..
Did you find that the H-pipe added any drone at all? I have the same magnaflow comp exhaust and like the fact that there is NO drone now. Would hate to loose that.
