If I wasn't still under warranty, I'd go the VAP route. Some of these piggyback tunes have spotty reputations, and I can't see any advantage of going this route over a ECU flash outside of warranty eligibility.

 

Which is a huge advantage for those of us with years left on warranty. As far as I’m concerned it’s either a mod that can be removed without a trace or no mod. Not willing to risk the warranty. But that’s just me. Others may feel different.

 

Jaggyx - is your car lowered? It looks awesome.

 

I don’t believe we’ve ever had someone on this forum denied a warranty claim because of a VAP tune. We have seen at least one of the other tunes denied a claim, but that was because the oil level was not checked when the tune was applied and then immediately put on a dyno (perhaps the most severe testing of an engine: inadequate airflow, etc.) For me, a 75hp increase was certainly worth the risk. For a base, a 110hp gain (tune & pulley) makes the benefit/risk ratio even more attractive. However, it’s all a matter of personal risk aversion.

 

75hp increase ? who did the map

 

I share the same sentiment. I still have a year of warranty left and thus have left my car untouched from an engine performance perspective although that might change soon.

Thanks. It is, Eibach springs with half a coil cut in the rear.

 

The VAP map takes the base and S to 425hp and the lower pulley adds another 25 (450hp). Map plus 2 pulleys takes power out to a total of 455 hp but I would not recommend that as the power drops off as you approach redline with the upper pulley. If I could find an OEM pulley, I’d revert back.

 

I understand now , with you getting the pulley done to . any enquires i made on a Map , I was told only a increase of 40 bhp could be achieved then adding on the pulley an extra 20 bhp would take mine to 560 bhp but would cost over a £1000 to do so . A lot of money for little gain in my mind hence the race chip at £345

 

Map 5 has a kick to it Will try 6 and 7 over next week if it ever stops raining

 

Plan to fully test race chip this weekend and give honest opinion . Weather has been lousy to date hence late post

 

Sorry for the delay in trying out this race chip , But weather has been lousy up until today . Firstly i had bought the middle RS version coming in at around £350 nearly $500 . It comes with 6 maps on it and is set to map 4 . maps 1,2,and 3 In my opinion were not any good . No difference to the car in both performance or torque . Map 4 factory setting . In my opinion a slight increase of torque , But it seemed to hold the revs very high for a more than normal period . Map 5 . i like this one . could feel better performance and torque , threw the head back slightly more lol . But i noticed my mpg was down in normal driving mode 30-50mph zone to 18.5 mpg instead of the 20-24 mpg i normally get . Map 6 no difference from map 4 in my opinion . so Map 5 seems to be the one for my car . but i wonder why my mpg has fallen and not increased as race chip promises to do. was asked for my opinion and this is it. i shall leave it on the car in map 5 .

 

Any concern about all that extra fuel going thru your cats?

 

Does the manufacturer explain the specific purpose for each of the 6 tunes, or do they just say “here are a bunch of tunes...use the one that feels best”?
If the latter ... not a very scientific approach. I also have a number of tunes from VAP, but each has a specific purpose.

 

I never thought of that , If it starts to give any problems i will take it off

 

Spot on lol although it is set to map 4 but done nothing for me

 

Racechip is a great tune for F-Types. If you want something easily installable and removable and undetectable, it takes about an hour to install the first time because the back sensor is under the wire harness on the driver side of the engine firewall. After you have a feel for the sensor location, it takes about 5 minutes to fully remove or install, and it leaves no trace in the engine management software because Racechip intercepts and alters sensor signals after the ECU.

Another good option is adding an upper pulley for around $250. Installation is easy with a custom Jag/LR SC pulley removal tool, very hard without one. An experienced dealer will be able to tell that the pulley is slightly smaller and mine is black instead of silver, but most don't have the experience or desire to tell the difference. Its somewhat hidden by intake tubing. I've have had warranty work done, including having the firmware updated and the dealer never mentioned my removed Racechip or my installed SC pulley.

Results:

Stock = 487 WHP / 460 Torque
SC Pulley no tune (WHP) = 506 WHP / 480 Torque
Stock + Racechip GTS Black Map = 535 WHP / 505 Torque
Racechip GTS Black Map 7 + SC Pulley = 555 WHP / 520 Torque

Peak WHP gain anywhere across the RPM band w/Racechip is about 70 HP eyeballing it.

Assuming 10% drivetrain loss, Racechip nets you 594 HP / 561 Torque
Assuming 10% drivetrain loss, Racechip + SC Pulley nets you 616 HP / 578 Torque

Assuming 15% drivetrain loss, Racechip nets you 629 HP / 594 Torque
Assuming 15% drivetrain loss, Racechip + SC Pulley nets you 653 HP/ 612 Torque

Assuming 20% drivetrain loss, Racechip nets you 669 HP / 631 Torque
Assuming 20% drivetrain loss, Racechip + SC Pulley nets you 694 HP / 650 Torque

These numbers are no issue for your ZF8.

Hope this helps answer your question!

 

Forgot to mention that's a 495 HP V8 S.

 

Thanks a bunch for the information. I think I’m gonna pull the trigger and buy a Race Chip. Not that I need the additional HP or performance, but I don’t “need” an FType either. Well maybe I do. 🤔 😊
I’m new to the forum and have to say that the members here seem very knowledgeable and, well, like nice guys. I also own a Corvette and spend limited time on that forum. It seems you can hardly make it through a thread without someone being negative about something. There are some good, knowledgeable folks there as well but the overall vibe is kinda different. Thanks.

 

I am happy with it so it stays on mine

 

Has anyone on this forum installed the Racechip on a Base 340 or S 380? I'm interested and curious about the installation procedures/difficulty and power increase results.
