Hi Guru's,
Right, made my mind up on the JP Exhaust. I think the TVR Power Exhaust is going to be a little too loud and it's more expensive
although like the look of it 
(Dom advised too loud with Decats). So, with the little chappy on it's way (fitted near me), i'm pondering what to do next, and have been advised a Remap, which I have been told is going to offer benefits.
I can see 2 options:
1. The Chip that TVR Power Offers, which I presume is preconfigured (What Benefits?) - Install and No Remap = Lower Cost
2. Remap of T350T either at TVR Power or Austech Benefits? - Do they do the same Remap? Any Differences? TVR Power is much closer to me, so favouring, although I think slightly more expensive than Austech, however with petrol cost (round trip to Austech 160miles more), probably makes no difference or cheaper to do TVR Power.
Thanks,
Steve

Not used either but TVR Power come highly recommended on these pages.
Not heard great things about the other mob. (I've asked a few questions via PM, as I was tempted to use them as they are probably my most local TVR "specialists")
I have a full JP big bore exhaust system with de-cat chip.
I'd rather have a custom map as each engine is slighty different so a bespoke map is better, but as you say it does come at a cost.
If I were you I'd use Power.
Good luck, and let us know the results

I'm in a similar position. Recently bought a T350 and am starting to look for things to tinker with.
I'm about to put the sports exhaust from Racing Green on mine, they are local to me, and I think its actually a bit cheaper than the other options too. I haven't heard of the JP one - maybe you could send me a link so I can compare?
On remaps... I would like to do the same, however due to me chatting with the boys at Racing Green whilst waiting for various things to be fixed, I'm more sold on the Syvecs system.
I don't know what a standard remap costs (I'm guessing £300ish if my X5 is anything to go by) but the Syvecs is vastly more - but it gives you a lot more too.
Whilst I don't particularly want it, it gives the car traction control. I suppose its good to have in case I let any friends take it for a spin...
Here in no particular order are some of the other benefits as best I can remember them:
- Cold start mode. Gives the car a richer blend on start up, so you don't have to balance the throttle to maintain idle. Basically acts like a choke.
- Sensors to detect detonation / knocking. My understanding is that if there is anything going wrong it will realise and stop any damage from taking place
- Sequential sparking
- 8 different engine maps selectable via a dial.
- eg: valet parking / wife map (eg max revs of 3000rpm), very wet conditions map (with max traction control), motorway map (lean burn - apparently can considerably extend range/mpg), normal mode, normal without T.C., Hooligan mode (over fueling to give pops, bangs and flames and a tiny bit more power).
- Set up includes an extensive rolling road session where its programmed to suit the particular car - any problems you may not be aware of will come to light
- I've been told that if I have the FFF head put in at a later stage the system will be reprogrammed again to suit the new engine as part of the package.
On balance, I think its a better all round system to take forward. My car suffers with fueling issues, flooding etc, and the syvecs apparently would sort that out too.
There are some other threads on the Speed Six forum that discuss this in far greater detail, or give the guys at RG a call. Like all the other TVR garages I've spoken to, they are very friendly and passionate about what they do.

Im interested in hearing how you get on with the syvecs system when you get it and how much it costs.
As for the remap chip when I first bought my T350 jools told me they came out of the box pretty well set up to begin with. A generic chip for a decatted engine will clean up the torque and power curves and a bespoke map is only really needed if you want the max power out of your car, in which case dont get the exhaust pipes and decat done as you will never get on track due to the noise.

I had mine remapped back around 2005. Made a difference. But to be honest the biggest outright performance difference I have noticed is from changing the final drive ratio in the diff. It makes the car 'on cam' much more often. Big difference. Second biggest was the full big bore exhaust system from Act. This makes a clear difference at over 5,000 rpm, the engine feels much freer, Jason from Str8Six said it would and he is right. Not 100s of HP but worthwhile IMO.
So, remapping is possibly not the best option as a first step. IMO.

what ratio did you go for in the diff 3.7/3.9 and what has it done for fuel consumption at mway speeds/cruising
3.91. Lots about this on here, do a search over several years.About + 10% more revs I think, so same increase in consumption. I ran from home to Brussels on one tank, refueled and measured over 26mpg running at 130-140kph. So not a problem IMO. I think I average low 20s, but only check on a very long run if I'm bored (rare in a TVR).

From London to Brussels on 1 tank, although it sounds further than it is (about 370km so 290 miles) I think it's still very good... Not sure I can get more than 250 miles out of my T350t.

by the way, may I complement you on a very nice T350t :-)
Any idea how many other Formula Red T350t's were build? Yours, mine,....?

Red Glow if you don't mind :-) I think there are 3-4 Red Glow Targas. I know of one other. Probably less Formula Red.by the way, may I complement you on a very nice T350t :-)

High Wycombe to Brussels, on around 46-7 litres actually. Don't like to drop much below 10 litres when on a long trip just in case! Like I said, over 26mpg.

cognitive dissonance made me appreciate my Formula Red one as well ;-)

Custom map as on rollers? or custom map on engine dyno?Not heard great things about the other mob. (I've asked a few questions via PM, as I was tempted to use them as they are probably my most local TVR "specialists")

Got to say the temperatures in that engine bay when it's on the rollers would make me wonder at the benefits of a custom map.
