No Computer Tuning of vehicles built elsewhere

No Computer Tuning of vehicles built elsewhere

May 20th 2016 - We would like to reiterate that EnglandGreen will NOT computer tune ANY vehicle built elsewhere. After bending our rule, once again - as usual - we were bitten in the behind. No more!!! Sorry for the inconvenience caused, but there will be zero exceptions from now on.

We are sorry, but we will only computer tune if it is stock or built by EnglandGreen. That is the line. We spend way too much time fixing leaking exhaust, vacuum leaks, O2 sensors not responding, cracked spark plugs, broken spark plug wires, incorrectly routed PCV system, rockers not torqued down, incorrect pushrod length... the list is almost infinite. And this is just from "bolt-on" cars. Add a cam, stall, blower, meth, fuel system etc. and it just gets worse and worse and worse. Again, we apologize for this change in policy but it has become necessary.

Delay in vehicle delivery clarification

Delay in vehicle delivery clarification

Over the past few years, some customers have voiced concerns over delivery dates slipping. This is completely understandable and we would like to clarify why this happens.

Please understand that we have no control over our vendors and they know it; the Corvette aftermarket is a very small segment of the larger performance market and the number of reputable vendors is extremely limited. As such, we are bent over a barrel by our vendors with no recourse like “taking our businesses elsewhere” because there is no “elsewhere" to go to.

It is important to note that we do everything in our power to deliver a quality product on time and within budget.

With very few exceptions, the primary reasons for missed delivery date are as follows :

EnglandGreen is not responsible for any delays caused by unavailability of parts, correct parts ordered but incorrect parts shipped, manufacturer defects, third party delays or delays in parts shipments by a supplier, courier company or transporter. 

EnglandGreen no longer tuning vehicles built elsewhere

EnglandGreen no longer tuning vehicles built elsewhere.

Effective November 13th 2013, EnglandGreen will no longer be offering computer software tuning services for vehicles built elsewhere. 

Over the years we have encountered far too many poor installations that invariably get blamed on “the tune” and EnglandGreen ends up owning all of the inherited problems with these vehicles. 

We regret this significant change in policy but we cannot continue owning other people’s problem vehicles, especially at no charge.

Modifications Primer

Corvette Modifications Primer : A few things to consider if you wish to modify your Corvette for High Performance. 

So you want to modify your C6 or C5 Corvette for high performance. Here are some things that you should consider first. 

What is your driving style? Are you a drag racer? Autocross? Road racer? Weekend warrior? Show car? Stoplight to stoplight? Or simply highway fun? Or a combination of all or some of these choices? 

How you drive and enjoy your Corvette will directly determine what modification you should make to your Corvette. 

Nothing is free. Every modification you make to your stock Corvette will involve some kind of compromise. You are not going to make 800 rear wheel horsepower and get 30 miles per gallon with a whisper quiet exhaust as well as drive and idle like stock. That is not going to happen. 

The trick is to be totally honest with yourself and decide what compromises you can live with and which ones you cannot. For example, if you want to achieve 500rwhp naturally aspirated, expect a big cam with a loping idle. Expect to lose some fuel efficiency. Expect your Corvette to not drive like stock. 

You can start with simple bolt-ons like an aftermarket air filter, long tube headers and cat-back exhaust system. The next logical step is a camshaft only upgrade or heads and camshaft. Along with the bolt-ons, you can be comfortably at the 425-450rwhp range, all naturally aspirated. Or you could bypass the bolt-ons and simply have a supercharger or twin turbocharger system installed. An alternative to bolt-on might be rear gears (along with a stall converter for the automatics). Gears can also compliment your other modifications. 

It all depends on what you wish to achieve. 

As you increase the stock Corvette from it's 300-340rwhp (C5-C6) or 435rwhp (C6 Z06) to circa 550rwhp on the stock bottom end, expect to have to upgrade other aspects of your drivetrain, cooling and suspension. Remember, nothing is free. 

Beyond 550rwhp, we strongly recommend a forged engine as you will be on borrowed time. At this point, your clutch/stall converter will have to be upgraded along with torque tube connectors, transmission and differential. Cooling must be addressed as well as the always overlooked and often forgotten bulletproof fuel system. At this point, methanol injection for boosted applications is almost mandatory. Suspension, brakes, wheels and tyres should also be seriously addressed, along with additional safety systems like a 6 point or better rollcage and so on. A Corvette that is very fast is no fun if it also does not handle and stop. 

High performance is not a cheap hobby and it is best to be very aware of this fact going in so you do not encounter any surprises. 

But no matter what your budget, we can tailor a system to suit your current and future needs. So please drop us a line or give us a call to discuss your Generation 5 & 6 Corvette high performance needs.
