Which (If any) Chip would you run? S4S


Recommended Posts


S4S - has 3 inch cat-less exhaust, alunox manifold, BOV, larger 2ndry injectors (RC)....

I was going to run Chip 3 - high torque as I won't track it much....

Is there a better chip for my set up? Or should I play it safe and stick with the stock map?

Thanks for any input!

I ran that chip in my S4s & she would spin the wheels in third on a good dry road when the turbo started boosting, great fun but had to be bery careful in the wet. 😃

I have a chip No.3 fitted. My main reason for fitting it was to smooth out the GM stumble that I had with the standard S4s chip. It makes things slightly more lively, but not ridiculously so, and I have to say that I’m very pleased with it. I didn’t go any further up the numerical chip tree, because the GM MAP sensor cannot read beyond 1 bar of turbo boost, and I didn’t want to risk damage to my engine. I think that if you get beyond that boost figure, you’re into the unknown, and a stand-alone ECU is arguably the next step. Any more torque, and it’s time to look at the gearbox, too.

Hey, with accl. pedal half way to the floor and 0.7 bar I'm already flying at a ridiculous (scary) speed with stock chip, (but w/gutted triple ball bearing turbo).

With "normal" driving you may never reach 0.9Bar!  Unless...you rent a runway at the local airport, LOL.

PS. Pitch the POS OEM restrictive turbo, than no need for chip.

BTW, I have one modified turbo available for sale. Looks very innocent, completely "stock"...until you open it. PM me, if interested.
